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: Wrong Answer)

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


public class Main {
	public static void main(String[] args) throws IOException{
		InputStreamReader is = new InputStreamReader(System.in);
		BufferedReader br = new BufferedReader(is);

		int n = 0;
		int kotae = 0;
		String temp = br.readLine();//a+b+c+dで表す値
		if(temp==null ||temp.length()==0 ){
			return;
		}
		n = Integer.parseInt(temp);

		if(n <= 36 ){
			for(int a=0;a<=9;a++){
				for(int b=0;b<=9;b++){
					for(int c=0;c<=9;c++){
						for(int d=0;d<=9;d++){
							if((a+b+c+d) == n){
								kotae++;
							}
						}
					}
				}
			}
		}
		System.out.println(kotae);
	}
}
