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 sc=new Scanner(System.in);
		while(sc.hasNextInt()){
			int n=sc.nextInt();
			int cnt=0;
			for(int i=0;i<10;i++){
				for(int j=0;j<10;j++){
					for(int k=0;k<10;k++){
						for(int l=0;l<10;l++){
							if(i+j+k+l==n)cnt++;
						}
					}
				}
			}
			System.out.println(cnt);
		}
		sc.close();
	}
