Write a program which reads an integer n and identifies the number of combinations of a, b, c and d (0 ≤ a, b, c, d ≤ 9) which meet the following equality:

a + b + c + d = n

For example, for n = 35, we have 4 different combinations of (a, b, c, d): (8, 9, 9, 9), (9, 8, 9, 9), (9, 9, 8, 9), and (9, 9, 9, 8).



Input

The input consists of several datasets. Each dataset consists of n (1 ≤ n ≤ 50) in a line. The number of datasets is less than or equal to 50.

Output

Print the number of combination in a line.

Example

Input

35
1


Output

4
4
#include <bits/stdc++.h>
using namespace std;


int dfs(int c,int s){
    if( c == 0 ) return s == 0;
    int ans = 0;
    for(int i = 0 ; i < 10 ; i++){
        ans += dfs(c-1, s-i);
    }
    return ans;
}

int main() {
    int n;
    while(cin >> n) cout << dfs(4, n) << endl;
}
