    int n;
    cin >> n;
    int ans = 0;
    int a[4] = {25, 10, 5, 1};
    for(int i = 0; i < 4; i++){
        ans += n/a[i];

}

### Prompt

Your challenge is to write a Cpp solution to 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

```cpp
#include<iostream>
using namespace std;

int main(){
    int n;
    cin >> n;
    int ans = 0;
    int a[4] = {25, 10, 5, 1};
    for(int i = 0; i < 4; i++){
        ans += n/a[i];
        n %= a[i];
    }
    cout << ans << endl;
    return 0;
}
