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 Python3 (judge verdict: Wrong Answer)

for _ in range(50):
    try:
        n = int(input()) # 1 <= n <= 50
        ans =set()
        for a in range(10):
            if (n - a) >= 1:
                for b in range(10):
                    if(n - a -b) >= 1:
                        for c in range(10):
                            if(n - a - b - c) >= 1:
                                for d in range(10):
                                    if(n - a - b - c - d) == 0:
                                        ans.add("{},{},{},{}".format(a,b,c,d))
        print(len(ans))
    except EOFError:
        break
