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.io.BufferedReader;
import java.io.IOException;
import java.io.InputStreamReader;


public class Main {
	
	public static void main(String[] args)throws IOException{
	
		BufferedReader br = new BufferedReader(new InputStreamReader(System.in));
		int[] intAry = new int[51];
		
		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++){
						intAry[i+j+k+l]++;
					}
				}
			}
		}
		
		String input;
		while((input = br.readLine()) != null){
			System.out.println(intAry[Integer.parseInt(input)]);
		}
	}
}
