Problem:
Sum of 4 Integers

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.

Sample Input

35
1

Output for the Sample Input

4
4

Solution in JavaScript (judge verdict: Wrong Answer)

var input = require('fs').readFileSync('/dev/stdin', 'utf8');
var lines = input.split('\n');

var line;
while (line = lines.shift()) {
  var cnt = 0;
  var num = +line;
  console.log(line);
  console.log(num);
  for (var i1 = 0; i1 < 9; i1++) {
    for (var i2 = 0; i2 < 9; i2++) {
      for (var i3 = 0; i3 < 9; i3++) {
        for (var i4 = 0; i4 < 9; i4++) {
          if (i1 + i2 + i3 + i4 == num)
              cnt++;
        }
      }
    }
  }
  console.log(cnt)
}
