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 n = sc.nextInt();
		int count = 0;
		for(int i=0;i<10;i++)
		{
			for(int j=0;j<10;j++)
			{
				for(int p=0;p<10;p++)
				{
					for(int q=0;q<10;q++)
					{
						if(i+j+p+q == n) count++;
					}
				}
			}
		}
		System.out.println(count);
	}
