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 Ruby (judge verdict: Accepted)

class Combi
  def initialize(sum)
    @sum = sum
  end

  attr_accessor :sum

  def calc(num)
    ret = 0

    (0..9).to_a.repeated_permutation(num).each do |ary|
      ret += 1 if ary.inject(:+) == @sum
    end

    return ret
  end
end

while line = gets
  puts Combi.new(line.to_i).calc(4)
end
