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<iostream>

using namespace std;
int n;
int bfs(int now,int d){
	int ans=0;
	if(d==4){
	if(now==n)return 1;
	else return 0;
	}
	else{
	for(int i=0;i<10;i++)ans+=bfs(now+i,d+1);
	}
	return ans;
}

int main(){
	while(cin>>n)cout<<bfs(0,0)<<endl;
