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.

Example

import itertools
try:
    while(True):
        n = int(input())
        cnt = 0
        rng = range(10)
        for i,j,k,l in itertools.product(rng,rng,rng,rng):
            if i + j + k + l == n:
                cnt = cnt + 1
        print(cnt)
except:
    pass
