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: Time Limit Exceeded)

while n=gets.to_i
	if n==nil
		break
	end
	count=0
	for a in 0..9
		if a > n
			break
		end
		for b in 0..9
			if a+b > n
				break
			end
			for c in 0..9
				if a+b+c > n
					break
				end
				for d in 0..9
					if a+b+c+d == n
						count+=1
#						puts "#{a} #{b} #{c} #{d} #{count}"
						break
					end
				end
			end
		end
	end
puts count
