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

Solution in Ruby (judge verdict: Wrong Answer)

while n = gets
  n.chomp.to_i
  m = 0
  (0..9).each do | i |
    (0..9).each do | j |
      (0..9).each do | k |
        (0..9).each do | l |
          if ( i + j + k + l == n )
            m += 1
          end
        end
      end
    end
  end
  puts m
end
