Problem Solving Repository

Welcome to my Problem Solving Repository! 🚀
This repository contains coding problems solved using complex data structures and algorithms from various competitive programming contests and independent practice. It serves as a record of my journey, tracking progress, and showcasing solutions to challenging problems.

Topics Covered

The problems here involve advanced concepts such as:

• Graph Algorithms (BFS, DFS, Dijkstra, Bellman-Ford, etc.)
• Dynamic Programming
• Segment Trees, Fenwick Trees
• Trees and Binary Search Trees
• Heaps, Priority Queues
• Hashing Techniques
• Advanced Sorting and Searching
• Mathematical & Number Theory Problems

Platforms Practiced On: [CSES, LeetCode, Phitron Contest, AtCoder, Code Ninja 360, CodeChef, Codeforces, GeeksforGeeks, Online Judge]

Languages Used

Most problems are solved in C++, which is my primary language, with occasional use of other languages:

  C
  C++ (Primary – Major Problem Solving)
  Python
  Go
  JavaScript
