Introduction

This repository contains a wide range of DSA practice problems that cover different topics and difficulty levels. The problems are designed to be solved using popular programming languages such as Python, Java, C++, and more. Each problem is accompanied by a clear problem statement, input/output specifications, and example test cases to guide you through the problem-solving process.

The practice problems in this repository are carefully crafted to cover a variety of concepts, including but not limited to:

• Array manipulation
• Linked lists
• Stacks and queues
• Trees and graphs
• Sorting and searching algorithms
• Dynamic programming
• Recursion
• Backtracking
• And more!
