LeetCode Solutions

This repository contains LeetCode problems that I have solved.
All the solutions present here are written by me while practicing on LeetCode and are pushed to GitHub automatically.

About This Repository

  • This is my personal LeetCode practice repository
  • It contains solutions of problems that I solved on LeetCode
  • The main goal of this repository is:
    • To track my problem-solving practice
    • To revise solutions later
    • To improve my Data Structures & Algorithms skills

How Solutions Are Added

I am using LeetSync for this repository.

  • Whenever I solve a problem on LeetCode
  • The accepted solution is automatically uploaded to this GitHub repository
  • No manual upload is required
  • Each solution belongs to a real LeetCode submission

Language Used

  • Java (main language used for solving problems)

What This Repository Contains

  • LeetCode Easy, Medium, and Hard level problems
  • Clean and understandable solutions
  • Logic written with learning and interview preparation in mind

Purpose

This repository is created to:

  • Practice LeetCode regularly
  • Maintain consistency in DSA
  • Help in revision before interviews
  • Keep all solved problems in one place

Note

  • These solutions are meant for learning and understanding
  • Do not blindly copy solutions
  • Try solving problems on your own first
