The signature of each function is provided below, do not make any changes to them otherwise the tester will not work properly. Keep in mind that you must not write a main body for your program. You should only implement these functions; it is the tester that will be calling and testing each one of them. The following are the functions you must implement: count_multiples(num1, num2, N) Description: Returns the number of multiples of N that exist between num1 and num2 inclusive. Parameters: num1 (int), num2 (int), N (int). num1 and num2 can be in any order. N cannot be 0. Return value: int Examples: count_multiples(2, 13, 3) → 4 count_multiples(17, -5, 4) → 6 count_multiples(-10, -5, -3) → 2 skip_sum(num1, num2, N) Description: Returns the sum of the integers between num1 and num2 inclusive but it skips every N th number in this sequence. Parameters: num1 (int), num2 (int), N (int). num1 and num2 can be in any order. N is always larger than 1. Return value: int Examples: skip_sum(2, 14, 3) → 70 # =2+3+5+6+8+9+11+12+14 | 4,7,10,13 skipped skip_sum(4, -3, 2) → 0 # =-3
