output_description: Print the number of combination in a line.
input_description: 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.

problem_description: 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).
