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

#include <iostream>
using namespace std;

int main(){
  int n,i,S;
  while(cin >> n){
    i = 0;
    for(S=0;S<=9999;S++){
      if((S/1000)+((S-S/1000*1000)/100)+((S-S/100*100)/10)+(S-S/10*10)==n)
	i=i+1;
    }
    cout<<i<<endl;
  }
  return 0;
