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: Wrong Answer)

arr = Array.new
renge = (0..9).to_a
while n = gets
   arr << n.to_i
end
arr.each do |i|
   count = 0
   renge.repeated_combination(4) do |a,b,c,d|
      if i == a + b + c + d
         count += 1
      end
   end
   puts 4 * count
end
