🚀 LeetCode Problem Solving Pattern

Welcome to my curated collection of LeetCode problems, organized by Problem-solving patterns, Data structures and Algorithms. This repository is part of my journey to master problem solving, competitive programming, sharpen my coding skills, and build a solid foundation in algorithmic problem solving.

🧠 Problem Solving Approach

Each problem in this repository is solved with clarity and efficiency, following a specific pattern or technique. Common strategies include:

🟢 Two Pointers
🔵 Sliding Window
🟣 Binary Search
🟣 Array & String
🔵 Linked list
🟣 Trees
🟢 Graphs
🟡 Depth-First Search (DFS)
🟠 Breadth-First Search (BFS)
🔴 Dynamic Programming
🟤 Greedy Algorithms
⚫ Backtracking
⚪ Bit Manipulation
🟩 Union-Find / Disjoint Set
🟦 Topological Sorting
🟥 Trie
🟣 Quick Sort, Merge Sort, Bucket Sort
...and more!

🗂️ Directory Structure

All solutions are grouped by the primary pattern or data structure used to solve them:

📁 Array/
📁 Backtracking/
📁 Binary_search/
📁 Binary_tree_bfs/
📁 Binary_tree_dfs/
📁 Bucket_sort/
📁 Graph_bfs/
📁 Graph_dfs/

Each folder contains:

✅ ProblemName.ext — Clean, well-commented solution
📝 A short description at the top of each file
📌 Time and space complexity analysis

📚 Languages Used

🟨 JavaScript
🟦 C++
🟩 Go

Depending on the problem or the goal of practice, I solve using different languages.

💡 Goals

Solve problems consistently following proven patterns.
Improve coding efficiency and readability.
Strengthen understanding of core DSA topics.
Maintain a searchable, well-organized archive of solutions.

📌 How to Use

Browse folders based on the topic you're interested in.
