This repository contains Java solutions to a wide range of LeetCode problems, curated from Striver's A2Z DSA Sheet. The goal is to build a strong foundation in Data Structures and Algorithms (DSA) using clean, readable, and optimized Java code.
Whether you're a beginner just getting started or someone preparing for coding interviews, this repo will serve as a valuable learning and revision resource.
Striver's A2Z DSA Sheet is a structured, topic-wise roadmap that guides learners from basic to advanced DSA concepts. It covers over 450+ handpicked problems across categories like:
- ✅ Arrays & Strings
- ✅ Recursion & Backtracking
- ✅ Linked Lists
- ✅ Stacks & Queues
- ✅ Binary Search, Sorting
- ✅ Trees & Graphs
- ✅ Dynamic Programming
- ✅ Greedy Algorithms & Tries
- ✅ Bit Manipulation and more
