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)

#coding: utf-8
STDOUT.sync = true

sum = Array.new(51, 0)
a = b = c = d = 10

a.times { |a|
  b.times { |b|
    c.times { |c|
	  d.times { |d|
	    sum[a + b + c + d] += 1
      }
	}
  }
}

while num = gets do
  puts sum[num.to_i]
end
