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 sum=0;
		while(sc.hasNext())
		{
			sum=0;
			int n= sc.nextInt();
			for(int i=0;i<=9;i++)
			{
				for(int j=0;j<=9;j++)
				{
					for(int k=0;k<=9;k++)
					{
						for(int a=0;a<=9;a++)
						{
							if((i+j+k+a)==n){sum++;System.out.println(a+" "+i+" "+j+" "+k);}
						}
					}
				}
			}
			System.out.println(sum);
		}
		

	}
