<h2>
 
 
 Problem 1: Contains Duplicate ( Leetcode 217 )
</h2>

Example: [ 1,2,2,4 ] Return True | [1,2,3] Return False

Solution: 

i) Brute Force

<code>n = len(nums) 
 for i in range(n): 
 for j in range(i+1, n): 
 if nums[i] == nums[j]: 
 return True 
 return False</code>

ii) Using Sort

If we sort the array, the duplicates will come close to each other, all that remains is comparing adjacent elements, this reduces the complexity from O(n^2) to O(n logn).

<code>nums.sort() 
 for i in range(len(nums)-1): 
 if nums[i] == nums[i+1]: 
 return True 
 return False</code>

iii) Using Set =&gt; This one honestly did not strike me at all at first. It reminded me that data structures and fundamentals of Python matter. A lot.

Sets do not allow duplicates. So if the length of our list = n and length of set(list) =&gt; No duplicates present, return False, else return True.

<code>if len(set(nums))==len(nums): 
 return False 
 else: 
 return True</code>

<h2>
 
 
 Problem 2: Missing Number (Leetcode 268)
</h2>

Example: [0,1,3] =&gt; 3 number, so range = [0,3] = [0,1,2,3] =&gt; 2 is missing | [0,1] =&gt; Range [0,2] = [0,1,2] =&gt; 2 is missing.

Solution

i) Brute Force

<code>n = len(nums) 
 for i in range(n+1): 
 if i not in nums: 
 return i</code>

ii) Sorting

Create the range according to length of nums [0,1,2,3] , now compare each element of range with sorted nums [0,1,3]

'nums.sort() 
 for i in range(len(nums)): 
 if nums[i] != i: 
 return i 
 return len(nums)`

iii) Math\Gauss Formula

Honestly, this felt satisfying when it clicked. Sum from 0 to n minus sum of array gives the missing number. 
0+1+2+3 =&gt; 6 
0+1+3 =&gt; 4 
6-4 = 2 =&gt; Missing number

<code>n = len(nums) 
 expected = n * (n + 1) // 2 
 actual = sum(nums) 
 return expected - actual</code>

iv) XOR Method 
Looked at this in LC solutions. Smart trick, but early on can feel confusing. Personally I will stick with the math one.

'res = 0 
 for i in range(len(nums)+1): 
 res ^= i 
 for num in nums: 
 res ^= num 
 return res`

Explanation: For XOR gate, x^x = 0 and x^0 = x. In this method we will keep a bucket (res in code). First we will take XOR with range. 
Current bucket = 0

Bucket | Range 

0 ^ 0 = 0 
0 ^ 1 = 1 
1 ^ 2 = 3 (Convert to binary then take XOR) 
3 ^ 3 = 0

Current bucket = 0 
Now we will take XOR with nums

0 ^ 3 = 3 
3 ^ 0 = 3 
3 ^ 1 = 2 
Final answer = 2

<h2>
 
 
 Problem 3: Find All Numbers Disappeared in an Array (Leetcode 448)
</h2>

This is kind of similar to Problem 1, I Used set logic here too.

<code>n = len(nums) 
 num_set = set(nums) 
 result = [] 
 for i in range(1, n+1): 
 if i not in num_set: 
 result.append(i) 
 return result</code>

<h2>
 
 
 Problem 4: Two sum (Leetcode 1)
</h2>

i) Brute Force:

<code>for i in range(len(nums)): 
 for j in range(i+1, len(nums)): 
 if nums[i] + nums[j] == target: 
 return [i, j]</code>

ii) HashMap Approach:

Store each number with its index in a dictionary while you iterate. For every new number, check if the target minus this number already exists in the dictionary. If yes, done.

This was my first time really thinking in terms of a hash map instead of just using Python dictionaries randomly. Felt good.

'seen = {} 
 for i, num in enumerate(nums): 
 rem = target - num 
 if rem in seen: 
 return [seen[rem], i] 
 seen[num] = i'

<h2>
 
 
 My Takeaway:
</h2>

Always start with brute force. Don’t start thinking of the optimal solution right away. You won’t be able to reach it unless you’ve already memorized it and that’s a different case. In interviews too, recruiters want to see your thought process, not just the final optimized solution. They want to see how, step by step, you eventually reach the optimal one, starting from brute force.

N8N Installation And Configuration

Setting Up a Self-Hosted n8n Automation Server on Ubuntu

This document outlines the end-to-end process of deploying the n8n automation platform on a fresh Ubuntu Server virtual machine using Docker. It also includes optional steps for adding a graphical user interface (GUI) for remote management.

Operating System: Ubuntu 24.04 LTS (Server Edition)

Part 1: Server and Prerequisite Setup

This section covers the initial server preparation, the optional installation of a desktop environment, and the mandatory installation of the Docker Engine.

Step 1.1: Virtual Machine (VM) Provisioning

<div class="highlight js-code-highlight">
<pre class="highlight plaintext"><code>An Ubuntu 24.04 LTS Server environment was chosen. This is a command-line-only operating system, which is lightweight and secure, making it ideal for server applications.
</code></pre>

</div>

Step 1.2: (Optional) Installing a Graphical Desktop Environment

The server operates via command line by default. For users who prefer a graphical interface for management, a desktop environment can be installed.

Note: This is generally not recommended for a production server as it consumes more system resources (RAM, CPU) and can increase the system's security attack surface.

<div class="highlight js-code-highlight">
<pre class="highlight plaintext"><code>Install the Ubuntu Desktop (GNOME): This command installs the standard graphical interface.
</code></pre>

</div>

Bash

sudo apt update

sudo apt install ubuntu-desktop -y

<div class="highlight js-code-highlight">
<pre class="highlight plaintext"><code>Install a Remote Desktop Server (xrdp): To access the graphical desktop from another computer, a remote desktop protocol (RDP) server is required. xrdp is a common choice.
</code></pre>

</div>

Bash

sudo apt install xrdp -y

<div class="highlight js-code-highlight">
<pre class="highlight plaintext"><code>Allow RDP through the firewall (if enabled): If you are using ufw (Uncomplicated Firewall), you must allow traffic on the RDP port.
</code></pre>

</div>

Bash

sudo ufw allow 3389

<div class="highlight js-code-highlight">
<pre class="highlight plaintext"><code>After these steps, you can connect to your server's IP address using any standard Remote Desktop Client (like the one built into Windows).
</code></pre>

</div>

Step 1.3: System Update

<div class="highlight js-code-highlight">
<pre class="highlight plaintext"><code>Ensure all system packages are up to date.
</code></pre>

</div>

Bash

sudo apt update &amp;&amp; sudo apt upgrade -y

Step 1.4: Docker Engine Installation

<div class="highlight js-code-highlight">
<pre class="highlight plaintext"><code>Install prerequisite packages: These are needed to allow apt to use repositories over HTTPS.
</code></pre>

</div>

Bash

sudo apt install ca-certificates curl gnupg

<div class="highlight js-code-highlight">
<pre class="highlight plaintext"><code>Add Docker's official GPG key: This verifies the authenticity of the Docker packages.
</code></pre>

</div>

Bash

sudo install -m 0755 -d /etc/apt/keyrings

curl -fsSL <a href="https://download.docker.com/linux/ubuntu/gpg" rel="noopener noreferrer">https://download.docker.com/linux/ubuntu/gpg</a> | sudo gpg --dearmor -o /etc/apt/keyrings/docker.gpg

sudo chmod a+r /etc/apt/keyrings/docker.gpg

<div class="highlight js-code-highlight">
<pre class="highlight plaintext"><code>Set up the Docker repository: This tells the system where to download Docker from.
</code></pre>

</div>

Bash

echo \

"deb [arch=$(dpkg --print-architecture) signed-by=/etc/apt/keyrings/docker.gpg] <a href="https://download.docker.com/linux/ubuntu" rel="noopener noreferrer">https://download.docker.com/linux/ubuntu</a> \

$(. /etc/os-release &amp;&amp; echo "$VERSION_CODENAME") stable" | \

sudo tee /etc/apt/sources.list.d/docker.list &gt; /dev/null

<div class="highlight js-code-highlight">
<pre class="highlight plaintext"><code>Install Docker Engine, CLI, and Compose:
</code></pre>

</div>

Bash

sudo apt update

sudo apt install docker-ce docker-ce-cli containerd.io docker-buildx-plugin docker-compose-plugin -y

<div class="highlight js-code-highlight">
<pre class="highlight plaintext"><code>Allow non-root user to run Docker (Post-installation): Add your user to the docker group to avoid using sudo for every command.
</code></pre>

</div>

Bash

sudo usermod -aG docker $USER

IMPORTANT: You must log out and log back in for this change to take effect.

Part 2: n8n Application Deployment with Docker Compose

This section details the deployment of the n8n application container.

Step 2.1: Create a Project Directory

<div class="highlight js-code-highlight">
<pre class="highlight plaintext"><code>Create and enter a dedicated directory to store n8n configuration and data.
</code></pre>

</div>

Bash

mkdir n8n-selfhosted

cd n8n-selfhosted

Step 2.2: Create the docker-compose.yml File

<div class="highlight js-code-highlight">
<pre class="highlight plaintext"><code>Using a text editor like nano, create the configuration file that defines the n8n service.
</code></pre>

</div>

Bash

nano docker-compose.yml

Step 2.3: Define the n8n Service

<div class="highlight js-code-highlight">
<pre class="highlight plaintext"><code>Paste the following configuration into the docker-compose.yml file. This setup ensures data is persisted in a Docker volume.
</code></pre>

</div>

YAML

version: '3.7'

services:

n8n:

<div class="highlight js-code-highlight">
<pre class="highlight plaintext"><code>image: n8nio/n8n:latest

restart: always

ports:

 - "5678:5678"

environment:

 - GENERIC_TIMEZONE=Asia/Kolkata

 - N8N_ENCRYPTION_KEY='YOUR_SUPER_SECRET_KEY_HERE'

volumes:

 - n8n_data:/home/node/.n8n

# Wait for container to be stopped before killing it

stop_grace_period: 1m
</code></pre>

</div>

volumes:

n8n_data:

Step 2.4: Customize Configuration

<div class="highlight js-code-highlight">
<pre class="highlight plaintext"><code>Timezone: The GENERIC_TIMEZONE was set to Asia/Kolkata to ensure scheduled workflows run at the correct local time.
Encryption Key: A unique and persistent N8N_ENCRYPTION_KEY is critical for securing credentials. A key was generated using the command below and pasted into the 'YOUR_SUPER_SECRET_KEY_HERE' placeholder.
</code></pre>

</div>

Bash

<h1>
 
 
 Run this command to generate a key
</h1>

openssl rand -base64 32

Step 2.5: Launch n8n

<div class="highlight js-code-highlight">
<pre class="highlight plaintext"><code>From within the n8n-selfhosted directory, start the n8n container in detached mode.
</code></pre>

</div>

Bash

docker compose up -d

Part 3: Final Setup and Verification

This section covers accessing the UI and completing the initial setup.

Step 3.1: Access the n8n Web Interface

<div class="highlight js-code-highlight">
<pre class="highlight plaintext"><code>The n8n instance is accessible via a web browser at:
</code></pre>

</div>

http://:5678

Step 3.2: Create the n8n Owner Account

<div class="highlight js-code-highlight">
<pre class="highlight plaintext"><code>Upon first access, the setup screen prompts for the creation of an owner (admin) account with a username, email, and password. This completes the installation.
</code></pre>

</div>

Part 4: First Workflow Creation (Beginner's Guide)

A simple workflow was created to learn the core concepts of n8n.

<div class="highlight js-code-highlight">
<pre class="highlight plaintext"><code>"Hello World" with the Set Node: A workflow was created with a Manual trigger and a Set node to create a static JSON object ({"message": "Hello..."}). This demonstrated the basic build-and-execute cycle.
Connecting to an API with the Weather Node:
 The Weather node was added to the workflow.
 A new credential was created for the OpenWeatherMap API by providing a free API key.
 The node was configured to fetch the current weather for "Bengaluru". This demonstrated connecting to external services and managing credentials.
Automating with the Cron Trigger:
 The Manual trigger was replaced with a Cron node.
 The schedule was set to run daily at a specific time (e.g., 9:00 AM).
 The workflow was activated using the toggle switch in the top-right, enabling it to run automatically in the background.
</code></pre>

</div>

Appendix: Common Management Commands

All commands should be run from the n8n-selfhosted directory.

<div class="highlight js-code-highlight">
<pre class="highlight plaintext"><code>Stop n8n: docker compose stop
Start n8n: docker compose start
View n8n logs: docker compose logs -f
Update n8n to the latest version:
</code></pre>

</div>

Bash

<h1>
 
 
 Pull the latest image from Docker Hub
</h1>

docker compose pull

<h1>
 
 
 Recreate the container with the new image
</h1>

docker compose up -d

<div class="highlight js-code-highlight">
<pre class="highlight plaintext"><code>Stop and remove the n8n container: docker compose down (Your data in the n8n_data volume will be p

reserved).
</code></pre>

</div>

Note: I am pretty new to the Ai, ML, Deep Learning stuff i am learning as i go.

Thoughts on Kimi K2 Thinking

For the past few weeks, I've been working on one of the coolest things I've ever pushed to production: a LeetCode-style platform for system design.

I've been writing about system design for a while now, and I genuinely love the topic (I talk about it weekly on my blog). I always wanted a tool to practice it without having to hunt down a billion references across the internet.

Every tool I found was either paywalled for the basics or completely abandoned. So, I built my own, and I have no intention of letting it go.

I believe this project has the potential to build a really great community. That's why I decided to "open-source" the entire platform. It's 100% open on GitHub, and I'm already creating issues for the next planned evolutions.

How this can help you: 
The idea is simple: just like LeetCode, you can submit your solution (with a diagram + textual explanation), and you can view and interact with solutions from others. No favoritism here—I truly believe there's no better way to prepare for an interview or just sharpen your skills.

I don't plan to fully "productize" this until I hit my first major goal, so feel free to play around as much as you want, and please let me know if you find any bugs.

How you can help me: 
First and foremost, dropping a star on the repository is a huge boost. That alone is massive support.

But if you want to help on a deeper level, feel free to open issues or even pull requests to add new features or work on existing ones. Honestly, the potential of this platform is not something I have enough bandwidth to explore alone.

Finally, spreading the word is also a big help. I want this to reach as many people as possible who need it.

Cheers!

If it gets some traction, I'll share the next steps for the roadmap.

To build and develop a web-based system, you sometimes need to be able to interact with a powerful JavaScript library. These libraries can be tools for building web games or tools for creating advanced charts. For example, you might use libraries like Three.js to create 3D environments, Chart.js or D3.js for data visualization, or Phaser for building 2D games. Choosing the right library depends on the project needs, the level of customization you expect, and the functionality you want to provide. At <a href="https://elanat.net" rel="noopener noreferrer">Elanat</a>, in version 2 of <a href="https://github.com/webforms-core" rel="noopener noreferrer">WebForms Core</a> technology, we have added powerful features for interacting with external JavaScript libraries.

</ul>

In WebForms Core technology, you can interact with JavaScript libraries through server-side code (in the WebForms class on the server and using a programming language on the backend). Interestingly, WebForms Core offers broader and more powerful features than front-end frameworks such as React, Vue, and Angular; however, because the foundation of front-end frameworks is built on the client side, developers cannot distinguish between the features and capabilities of these frameworks and the independent JavaScript structure.

<h2>
 
 
 Module Support
</h2>

In version 2 of WebForms Core technology, the ability to dynamically invoke JavaScript modules has been added. This feature allows the necessary scripts to be loaded only when needed, based on server-side execution logic or user state, without including the entire set of scripts in the page by default. In this way, the performance of the application is increased and the amount of data transferred to the browser is reduced. In addition, developers can organize JavaScript modules in a modular and manageable way, and benefit from easier maintenance and independent updates of each part. This approach makes WebForms Core a more modern platform and equal to today's front-end architectures such as SPAs.

<blockquote>
Note: With a little ingenuity, it is even possible to dynamically extract JavaScript module functions from a script to consume less bandwidth (and not download the entire module). This is something you can do on the server, but you can't do on the client side!
</blockquote>

To call the module, you need to make sure that the type attribute in the WebFormsJS script tag is set to module. 


<div class="highlight js-code-highlight">
<pre class="highlight html"><code>&lt;script type="module" src="web-forms.js"&gt;&lt;/script&gt;
</code></pre>

</div>



Example: 


<div class="highlight js-code-highlight">
<pre class="highlight csharp"><code>form.LoadModule("/module/my-module.js", ["func1", "func2", "funcn"]);
</code></pre>

</div>



In the above method, we add the module using the module path. In the second part, we can specify the methods (functions) of the module that we need; if you do not specify the methods, all of them will be added in the modules section.

You can also remove the module and all of the module's methods by calling the "UnloadModule" method. 


<div class="highlight js-code-highlight">
<pre class="highlight csharp"><code>form.UnloadModule("/module/my-module.js");
</code></pre>

</div>



We can also use the "DeleteModuleMethod" method to delete module methods. 


<div class="highlight js-code-highlight">
<pre class="highlight csharp"><code>form.DeleteModuleMethod("func2");
</code></pre>

</div>



<blockquote>
Note: Please note that the structure of adding a module in dynamic mode in JavaScript is done async and WebForms Core commands are executed hierarchically. If you want to use its methods immediately in the same Action Control after loading the library, you must use the Condition structure. We will teach you this later in the article and in the section "Checking the existence of a method (function)".
</blockquote>

<h2>
 
 
 Calling methods in Action Control
</h2>

In this version, the "CallMethod" method and the "CallModuleMethod" method have also been added. This feature is for calling methods that we do not need their return value and simply want to perform an action by calling them.

Example: 


<div class="highlight js-code-highlight">
<pre class="highlight csharp"><code>form.CallMethod("alert", ["Hello WebForms Core!"]);
form.CallModuleMethod("func1", ["arg1", "arg2", "argn"]);
</code></pre>

</div>



<h2>
 
 
 Calling and assigning methods in the Fetch class on the server
</h2>

In the Fetch class on the server, it is possible to call and assign Module methods using the "ModuleMethod" method.

<blockquote>
Note: In version 2 of WebForms Core in the Fetch class on the server, the "CallMethod" method has also been renamed to "Method".
</blockquote>

This is to get the return value of the methods that we have called and we want to use these values.

Example: 


<div class="highlight js-code-highlight">
<pre class="highlight csharp"><code>form.SetValue("TextBox1", Fetch.ModuleMethod("FunctionName", ["arg1", "arg2", "argn"]));
</code></pre>

</div>



<h2>
 
 
 Assigning JavaScript methods in tag events
</h2>

In this version, we have added the ability to assign methods and module methods in tag events. Previously, we could only call JavaScript methods in the Fetch class on the server, but now we can do it much faster. This new feature allows us to assign JavaScript methods directly in the events of DOM elements in HTML, so we do not need to make additional requests to the server.

Example:

By using the following methods, you can add JavaScript functions from the server to the events of each element.

Set Method:

<ul>
<li>SetMethodEvent</li>
<li>SetMethodEventListener</li>
<li>SetModuleMethodEvent</li>
<li>SetModuleMethodEventListener
</li>
</ul>

<div class="highlight js-code-highlight">
<pre class="highlight csharp"><code>form.SetMethodEvent("&lt;body&gt;", HtmlEvent.OnLoad, "Method1");
form.SetMethodEventListener("Button1", HtmlEventListener.Click, "Method2", ["arg1"]);
form.SetModuleMethodEvent("&lt;p&gt;-1", HtmlEvent.OnClick, "Method3", ["arg1", "arg2"]);
form.SetModuleMethodEventListener("{my-class}", HtmlEventListener.DoubleClick, "Method4", ["arg1", "arg2", "arg3"]);
</code></pre>

</div>



Explain above code: 
Line 1: Assigns the method "Method1" to the body element's load event. 
Line 2: Assigns the method "Method2" with argument "arg1" to the click event of an element with id "Button1" 
Line 3: Assigns the module method "Method3" with two arguments to the click event of the last paragraph element. 
Line 4: Assigns the module method "Method4" with three arguments to the double-click event in first element with the class "my-class".

You can remove these event method assignments using comparable remove functions with the same parameter structures.

Remove Method:

<ul>
<li>RemoveMethodEvent</li>
<li>RemoveMethodEventListener</li>
<li>RemoveModuleMethodEvent</li>
<li>RemoveModuleMethodEventListener
</li>
</ul>
<div class="highlight js-code-highlight">
<pre class="highlight csharp"><code>form.RemoveMethodEvent("&lt;body&gt;", HtmlEvent.OnLoad, "Method1");
form.RemoveMethodEventListener("Button1", HtmlEventListener.Click, "Method2");
form.RemoveModuleMethodEvent("&lt;p&gt;-1", HtmlEvent.OnClick, "Method3");
form.RemoveMethodEventListener("{my-class}", HtmlEventListener.DoubleClick, "Method4");
</code></pre>

</div>

<h2>
 
 
 Checking for the existence of a method (function)
</h2>

In this version, we have added the ability to check for the existence of methods and module methods.

Example: 


<div class="highlight js-code-highlight">
<pre class="highlight csharp"><code>form.IsTrue(Fetch.HasMethod("FunctionName"), 100);
form.CallMethod("FunctionName");
</code></pre>

</div>



You can use the same thing for external module methods 


<div class="highlight js-code-highlight">
<pre class="highlight csharp"><code>form.IsTrue(Fetch.HasModuleMethod("FunctionName"), 100);
form.SetValue("TextBox1", Fetch.ModuleMethod("FunctionName", ["arg1", "arg2", "argn"]));
</code></pre>

</div>



<blockquote>
Note: WebForms Core technology is also available for all important programming languages ​​on the web. These programming languages ​​are slightly different from each other; even in different versions of themselves, there may be differences. The above code is suitable for C# version 12 and higher, and if you use a lower version of C#, you should initialize the arguments of the "ModuleMethod" method as follows: 

</blockquote>

<div class="highlight js-code-highlight">
<pre class="highlight csharp"><code>new[] {"arg1", "arg2", "argn"}
</code></pre>

</div>



<h2>
 
 
 Conclusion
</h2>

Calling custom JavaScript functions from the server side shows that WebForms Core retains the flexibility needed for specific client-side scenarios (such as interacting with a complex graph or performing native calculations). In this way, the developer can implement heavy processing logic or specific UI interactions without leaving the WebForms Core framework, and establish dynamic communication between the server-side and client-side parts. This feature allows the server's processing power to be combined with the dynamism of JavaScript in the browser, creating a smoother and smarter experience for the end user. Also, using this approach, it is possible to design reusable JavaScript modules that operate in full harmony with the life cycle of web pages and server-side events.
