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.Scanner;


public class Main {

	
	public static void main(String[] args) {
		Scanner stdIn = new Scanner(System.in);
		
		while(stdIn.hasNext()){
			int result = 0;
			int n = Integer.parseInt(stdIn.next());
			for(int a=0;a<10;a++){
				for(int b=0;b<10;b++){
					for(int c=0;c<10;c++){
						for(int d=0;d<10;d++){
							if(n == (a+b+c+d)) result++;
						}
					}
				}
			}
			System.out.println(result);
		}
		stdIn.close();
	}
