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 main(void) {
	int a,b,c,d,n,i;
	while(scanf("%d",&n) != EOF){
	i = 0;
	for(a = 0; 10 > a; a++){
		for(b = 0; 10 > b; b++){
	for(c = 0; 10 > c; c++){
	for(d = 0; 10 > d; d++){
		if(a+b+c+d == n)i++;
	}	
	}	
	}
	}
	printf("%d\n",i);
	}
	
	return 0;
