Leetcode Solutions

Description

This repository contains my solutions to the free problems on Leetcode. Since I do not have access to the premium version, the focus is solely on publicly available questions.

Problem Categories

The solutions cover a wide range of topics, including:

  • Arrays
  • Strings
  • Hash Tables
  • Graphs
  • And more!

Language

All solutions are implemented in Python, as I am currently focusing on mastering this language.

Contributions

Contributions are welcome! If you'd like to help improve the code or add new solutions, feel free to open a Pull Request (PR). Any feedback or suggestions for writing better code are highly appreciated.

Thank you!
