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.*;

public class Main{
	private static final Scanner scan = new Scanner(System.in);

	public static void main(String[] args){
		List<Integer> list = new ArrayList<Integer>();
		while(scan.hasNext()){
			int cnt = 0;
			int n = scan.nextInt();
			for(int i = 0; i <= 9; i++){
				for(int j = 0; j <= 9; j++){
					for(int k = 0; k <= 9; k++){
						for(int l = 0; l <= 9; l++){
							if(i + j + k + l == n){
								cnt++;
							}
						}
					}
				}
			}
			list.add(cnt);
		}
		for(int n : list){
			System.out.printf("%d\n", n);
		}
	}
