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: Wrong Answer)

import java.util.Scanner;

public class Main {

	public static void main(String[] args) {
		Scanner sc = new Scanner (System.in);
		int tem=0;
		while(sc.hasNext()) {
			int n = sc.nextInt();
			for(int i=9;i>=0;i--) {
				for(int j=9;j>=0;j--) {
					for(int k=9;k>=0;k--) {
						for(int l=9;l>=0;l--) {
							if(i+j+k+l == n)  tem+=1;
						}
					}
				}
			}
			
		System.out.printf("%d\n",tem);
		}
	}
