LeetCode Solutions

This repository contains my solutions to various LeetCode problems.
Solutions are written in C++, organized by problem number/title, and each problem folder usually includes:

• Source code (.cpp) with a main() for quick testing
• A short per-problem README.md (problem statement, examples, approach, and complexity)
• (Sometimes) a Makefile and helper headers (e.g., a custom Vector.h)
