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

Output for the Sample Input

Solution in Haskell (judge verdict: Accepted)

main = interact $ unlines.solve.map read.words

solve :: [Int] -> [String]
solve []     = []
solve (n:ns) = (show.length $ anslist):solve ns
    where anslist = [(a,b,c,d) | a <- [0..9], b <- [0..9], c <- [0..9], d <- [0..9], a+b+c+d == n]
