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 JAVA (judge verdict: Accepted)

import java.util.Scanner;

public class Main {
	static int DP(int n) {
		int COUNT = 0; 
		for(int a = 0; a < 10; a++)
			for(int b = 0; b < 10; b++)
				for(int c = 0; c < 10; c++)
					for(int d = 0; d < 10; d++) {
						if((a + b + c + d) == n)
							COUNT++;
					}
		return COUNT;
	}
	
	public static void main(String[] args) {
		Scanner sc = new Scanner(System.in);
		while(sc.hasNext()) {
			int n = sc.nextInt();
			System.out.println(DP(n));
		}
	}
}
