#include <iostream>
#define int long long
using namespace std;
signed main() {
	int n, ans = 0; cin >> n;
	ans += n / 25; n %= 25;
	ans += n / 10; n %= 10;
	ans += n / 5 + n % 5;
	cout << ans << endl;
}

### Prompt

In Cpp, your task is to solve the following problem:

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.

output
