Count 4-Digit Codes with Digit Sum Equal to S

google Sum of Four-Digit Codes Consider all codes made of four digits (0-9). Count how many of them have a sum of digits equal to an integer S. How many such codes exist? Examples S = 35, the resulting array is: [9998, 9989, 9899, 8999]. Therefore, the answer is 4. S = 27, the function should return 935. Assume: S is an integer within the range [0, 36].
