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

#include <stdio.h>
#define rep(i, n) for (int i = 0; i < (int)(n); i++)

int cnt[64];

int main() {
    rep (a, 10) rep (b, 10) rep (c, 10) rep (d, 10) cnt[a+b+c+d]++;
    int n;
    while (scanf("%d", &n) != EOF) printf("%d\n", cnt[n]);
    return 0;
