Algorithm & Data Structure Problems

This repository contains my solutions to algorithm and data structure problems, mostly from LeetCode.
The purpose is to practice problem-solving and build a strong foundation for coding interviews.

📂 Structure

• arrays/ – arrays & strings
• hashmap/ – hash maps & sets
• linked_list/ – singly & doubly linked lists
• stack_queue/ – stack, queue, monotonic stack
• binary_search/ – binary search techniques
• trees/ – binary trees & binary search trees (BST)
• graphs/ – graph traversal (BFS, DFS, topological sort)
• dynamic_programming/ – DP & optimization problems
• (folders will be filled step by step)

🚀 Notes

• Each file includes:
  • Problem link
  • Short explanation / approach
  • Time & Space complexity
