A comprehensive collection of my LeetCode problem solutions, organized by difficulty level. This repository serves as a record of my progress in mastering data structures and algorithms through deliberate practice.
The repository is organized by problem difficulty, with each problem stored in its own numbered directory:
leetcode/
├── contest/
│ └── first_context(474)/Q
├── easy/
│ ├── 1143/
│ ├── 118/
│ ├── 121/
│ └── ...
└── medium/
├── 1513/
├── 19/
├── 2/
└── ...
- easy/ - Easy difficulty problems
- medium/ - Medium difficulty problems
- Hard/ - Hard difficulty problems
- contest/ - Solutions from LeetCode contests
Each directory is named after the problem number and contains the solution implementation.
Python 3 - All solutions are implemented in Python 3 and C++, focusing on clean, efficient code with clear algorithmic thinking.
- Easy: 37 problems
- Medium: 31 problems
- Hard: 3 problem
- Contest: 1 contest participation
This repository aims to:
- Document systematic progress through LeetCode's problem set
- Provide a reference for revisiting problem-solving techniques
- Demonstrate proficiency in algorithmic problem-solving
- Build a portfolio of practical coding skills
These solutions reflect my approach to each problem, emphasizing clarity and efficiency. I continuously refine my solutions as I learn new techniques and patterns.
