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.InputStreamReader;
import java.io.IOException;

public class Main {

	public static void main(String[] args) throws IOException {
		new Main().run();
	}
	
	private void run() throws IOException {
		BufferedReader reader = new BufferedReader(new InputStreamReader(System.in));
		String str;
		while ((str = reader.readLine()) != null) {
			int ans = 0;
			int n = Integer.parseInt(str);
			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) {
								ans++;
							}
						}
					}
				}
			}
			System.out.println(ans);
		}
		reader.close();
	}
