About

This site provides clean, well-structured C# solutions to LeetCode problems and Java solutions to GeeksforGeeks POTD.

Why C#?

Most LeetCode solution repositories focus on C++, Java, or Python. High-quality, consistent C# solutions are hard to find. This site fills that gap with idiomatic .NET code that mirrors real interview expectations for .NET developers.

Why Java for GFG?

GeeksforGeeks Problem of the Day is one of the most popular daily coding challenges in India. Solutions here are in Java — the most widely expected language for GFG submissions — updated daily.
