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

Solution in Haskell (judge verdict: Accepted)

import System.IO

main :: IO()
main = do
  end <- isEOF
  if end then return()
  else do
    n <- readLn
    let xs = [a+b+c+d | a<-[0..9],b<-[0..9],c<-[0..9],d<-[0..9]] :: [Int]
        f x = length $ filter (==x) xs
        in putStrLn . show $ f n
