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 res;
int n;

void dfs(int u, int all)
{
	if(u == 4)
	{
		if(all == n) res ++;
		return;
	}
	
	for(int i = 0; i < 10; i ++ )
		dfs(u + 1, all + i);
}

int main()
{
	while(cin >> n)
	{
		res = 0;
		
		dfs(0, 0);
		
		cout << res << endl;
	}
}
