This repository contains my solutions to various Codeforces problems. All solutions are implemented in C++.

Codeforces Profile

Directory Structure

Solutions are organized in the /CODEFORCES PROBLEMS directory. Each file is named according to the problem ID and name.

Common Template

All solutions use a common template that includes:

Standard C++ libraries
Common macros and type definitions
Fast I/O optimization
Debugging helpers
Common constants and utility functions

Usage

Each solution can be compiled and run independently. The solutions are written to be submitted directly to Codeforces.

// Example compilation
g++ -std=c++17 solution.cpp -o solution
