# 🧠 My DSA Problem Solving
This is **not just a collection of code** — it’s a journey of how I solve problems, reflect on mistakes, improve my logic, and master algorithmic thinking step by step.
I use this repo to document my:
- ❓ Understanding of the **problem statement**
- 🔎 Initial **brute-force** logic
- ⚠️ **Mistakes** or wrong assumptions I made
- 🔧 **Corrections** and **debugging steps**
- ⚡ Final **optimized approach**
- 🧪 **Edge case analysis** and thought clarity
Each problem folder = 📂 One learning story.

## 📌 Repository Goals
> Solve with thinking, not just coding.
🔹 **Learn DSA deeply**, one real problem at a time
🔹 **Reflect and journal** my thought process
🔹 **Avoid copying** — solve from scratch with my logic
🔹 **Master problem patterns** via repetition and intuition
🔹 **Prepare for interviews** through conceptual clarity and coding confidence

## 🚀 My Current Focus: Top Interview 150 on LeetCode
🎯 I’m solving problems from the [**Leetcode Top Interview List**](https://leetcode.com/list/xi4ci4ig/) in the **same sequence as Apna College's DSA Playlist** to follow a structured roadmap.

## 📚 Resources That Guide Me
🎥 Apna College DSA Playlist
- 🔗 [Watch Here](https://www.youtube.com/playlist?list=PLfqMhTWNBTe0b2nM6JHVCnAkhQRGiZMSJ)
- 📋 I follow this playlist to plan my problem-solving topics in order (arrays → strings → recursion → etc.).
🧠 Nikhil Lohia - Algorithmic Paradigms
- 🔗 [Watch Here](https://www.youtube.com/playlist?list=PLiC1doDIe9rBzGkVgaR9XO_Jj4AA9Wio1)
- 📌 I watch this to think in terms of brute force → optimization and understand how to *design* an algorithm before coding it.
📖 O’Reilly: Data Structures & Algorithms by Michael McMillan
- 🔗 [Book Link](https://www.oreilly.com/library/view/data-structures-and/9781449364939/)
- 📘 I read this for strong conceptual foundations — especially on how data structures work under the hood.
🧩 Leetcode Top Interview 150
- 🔗 [Target List](https://leetcode.com/list/xi4ci4ig/)
- 🎯 This is my primary problem set right now — each solved problem goes into this repo.

## 📁 Structure of Each Problem Folder
Each problem I solve gets its own folder:
```
📂 /Problem-Name
┣ 📄 README.md ← My complete thought process, logic, mistakes & learnings
┗ 📄 index.js ← Final optimal solution (with clean code & comments)
```
