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

import java.util.*;



class Main{

	private static int sum_check(int a){

		int count = 0;

		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++){
						if((i+j+k+l) == a){count++;}
					}	
				}
			}

		}			

		return count;

	}

	

		public static void main(String args[]) throws IOException{

			Scanner scan = new Scanner(System.in);

			int n,count;

			

			while(scan.hasNext()){

				String str1 = scan.next();

				n = Integer.valueOf(str1).intValue();

				count = sum_check(n);

				System.out.println(count);

			}

		}
