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;

namespace SumOf4Integers
{
    class Program
    {
        static void Main(string[] args)
        {
            int input = int.Parse(Console.ReadLine());
            if (input > 36)
            {
                Console.WriteLine(0);
            }
            else if (input == 36 || input == 0)
            {
                Console.WriteLine(1);
            }
            else
            {
                int count = 0;
                int n = 9;
                if (input < 9)
                {
                    n = input;
                }

                for (int i = 0; i <= n; i++)
                {
                    for (int j = 0; j <= n; j++)
                    {
                        for (int k = 0; k <= n; k++)
                        {
                            for (int l = 0; l <= n; l++)
                            {
                                if (i + j + k + l == input)
                                {
                                    count++;
                                }
                            }
                        }
                    }
                }


                Console.WriteLine(count);
            }
        }
    }
