About

This repository contains my LeetCode,GeeksforGeeks, and competitive programming solutions, focusing primarily on the most optimal approaches for each problem but whenever applicable and feasible, I also explore alternative brute,better solutions to build a deeper understanding of different problem-solving techniques
