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

public class Main {

	public static void main(String[] args) {

		Scanner sc = new Scanner(System.in);

			int cnt = 0;
			int n = sc.nextInt();
			for (int a = 0; a <= 9; a++)
			for (int b = 0; b <= 9; b++)
			for (int c = 0; c <= 9; c++)
			for (int d = 0; d <= 9; d++)
				if (a + b + c + d == n) cnt++;
			System.out.println(cnt);
		}
