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)

# Sum of 4 Integers

require 'matrix'

ab = Matrix.build(10,10) do |i,j|
	i + j
end

abc = Matrix.build(10,10) do |i,j|
	ab[i,j] + j
end

abcd = Matrix.build(10,10) do |i,j|
	abc[i,j] + j
end 

n = gets.to_i
count = 0
abcd.each{|e| count += 1 if e == n}

puts count * 4
