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 <stdio.h>

int cnt, n, a, b, c, d;

int main(void)
{
  while(scanf("%d",&n) == 1)
  {
    cnt = 0;
    for(a = 0; a <= 9; a++)
    for(b = 0; b <= 9; b++)
    for(c = 0; c <= 9; c++)
    for(d = 0; d <= 9; d++)
      if (a + b + c + d == n) cnt++;
    printf("%d\n",cnt);
  }
  return 0;
