Leetcode C++ Solutions

This repository contains my personal solutions to various Leetcode problems, all written in C++.

The purpose of this repo is to track progress, improve problem-solving skills, and serve as a reference for future revision or interview prep.

🗂 Structure

All solutions are placed in the root directory of the repository. Each file is named after the problem it solves, typically in the format:

<ProblemName>.cpp

Examples:

• two_sum.cpp
• longest_substring_without_repeating_characters.cpp
• median_of_two_sorted_arrays.cpp

Feel free to explore the code for each problem directly.

▶️ How to Run a Solution

1. Clone the repository:

   git clone https://github.com/ghostreindeer09/leetcode.git
   cd leetcode

2. Compile and run any .cpp file using a C++ compiler (e.g., g++):

   g++ two_sum.cpp -o two_sum
   ./two_sum

   Make sure you have a C++17+ compatible compiler installed (like g++ or clang++).

⚠️ Note: Some files may contain just the core logic (e.g., class/function definitions) without a main() function. These are intended for use within the Leetcode online judge and may need a main() wrapper to run locally.

📌 Goals

• Practice daily Leetcode problems
• Improve algorithmic thinking and C++ skills
• Build a searchable archive of solved problems
