## Overview

This repository is a collection of independent C/C++ Toph competitive-programming solutions, not a shared application. The workflow is per program: a user or judge supplies problem input, the standalone solution computes an answer, and it prints that answer. Solutions are grouped by the repository’s Easy, Medium, and Hard directories. There is no shared runtime layer or inter-solution data flow; relationships shown are limited to each program’s input and output, as supported by its source.

Main entry points: [`Easy/Is Anagram.c`](https://github.com/being-fahim/toph-solution/blob/main/Easy/Is%20Anagram.c) (Anagram check), [`Easy/Is Palindrome.c`](https://github.com/being-fahim/toph-solution/blob/main/Easy/Is%20Palindrome.c) (Palindrome check), [`Medium/Cash Change.c`](https://github.com/being-fahim/toph-solution/blob/main/Medium/Cash%20Change.c) (Cash change), [`Medium/Incompatible Crops.c`](https://github.com/being-fahim/toph-solution/blob/main/Medium/Incompatible%20Crops.c) (Crop grid scan)
