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 C# (judge verdict: Wrong Answer)

using System;
class Program{
	static void Main(){
		int n = int.Parse(Console.ReadLine());
		if(n>36) Console.WriteLine(0);
		else{
			if(n>18) n = 36-n;
			int ans = (n+1)*(n+2)*(n+3)/6;
			if(n>9) ans -= (n-7)*(n-6)/2;
			Console.WriteLine(ans);
		}
	}
}
