# Code Challenges Repository
This repository contains my solutions to coding problems from platforms such as **LeetCode**, **HackerRank**, and others. Solutions are written primarily in **Python** and **C++**, with the potential to expand to other languages over time.
In addition to final solutions, I include failed attempts, error logs, and step-by-step debugging notes to document my thought process and learning journey.

- 📄 Per-problem `README.md` files to explain:
- Problem statement (summary)
- Thought process
- Why certain approaches failed
- Final solution and complexity analysis
---
## 🛠 Languages Used
- Python 3
- C++
- (More languages may be added later)
