### Prompt

Develop a solution in cpp to the problem described below:

You want to make change for $ n $ cents. Assuming that you have infinite supply of coins of 1, 5, 10 and / or 25 cents coins respectively, find the minimum number of coins you need.

Constraints

* $ 1 \ le n \ le 10 ^ 9 $

Input


$ n $


The integer $ n $ is given in a line.

2175

### Response

```cpp

#include<iostream>
#include<cstddef>


using ui32 = std::uint32_t;

int main(){

	std::uint32_t n;

	std::cin >> n;

	auto t{ n };
	ui32 ans{ 0 };

	const ui32 cents[4] = { 25, 10, 5, 1 };
	
	for( const auto cent : cents )
	{
		ans += t / cent;
		t %= cent;
	}

	std::cout << ans << "\n";
	return 0;
}
