|FEAT|: create main.cpp && algorithm analysis folder

[sotoJ24]

Create folder for Analyzing Big Algorithms in C++ (LeetCode & Coding Interviews)

Description

This PR introduces a new folder dedicated to analyzing and implementing large-scale algorithms in C++. The purpose is to provide optimized solutions commonly encountered in coding interviews (e.g., LeetCode, CodeForces, HackerRank). These implementations focus on efficiency, best practices, and real-world problem-solving techniques.

Changes Introduced

• 📂 Created a new directory: big_algorithms_cpp/
• 📌 Added initial documentation (README.md) outlining the scope of this folder.
• 🔢 Added [List of algorithms] (e.g., sorting, searching, dynamic programming, graph algorithms, etc.).
• 📝 Included example implementations with proper comments and complexity analysis.

Testing & Validation

• ✅ Compiled and tested initial implementations.
• ✅ Verified correctness and efficiency with multiple test cases.
• ✅ Ensured code readability and proper documentation.

Additional Notes

• Future updates will include more optimized versions of algorithms and explanations.
• Open for contributions! Feel free to improve existing solutions or add new ones.
