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: Time Limit Exceeded)

while n=gets.to_i
	v=[]
	10.times do |i|
		10.times do |j|
			10.times do |k|
				10.times do |l|
					if i+j+k+l==n
						v<<i
						v<<j
						v<<k
						v<<l
					end
				end
			end
		end
	end

	puts (v.length)/4
end
