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

Solution in JAVA (judge verdict: Accepted)

import java.util.Scanner;

class Main {
    public static void main(String args[]) {
        Scanner sc = new Scanner(System.in);

        while (sc.hasNext()) {
            int n = sc.nextInt();

            int nCombinations = 0;
            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)
                                nCombinations++;

            System.out.println(nCombinations);
        }
    }
}
