def speed_adjust(A: int, B: int, C: int) -> int:
"""
--------------------------------------------------------------------------------------------------
function determines if car B needs to speed up (1), slow down (-1), or maintain current speed (0)
--------------------------------------------------------------------------------------------------
First we find the distances between the cars by subtracting the car behind from the car ahead
-B is ahead of A, so B-A, and C is ahead of B, so C-B
Then we use simple logic to determine what our middle car needs to do, and return the appropriate result
-If the distance between the cars is the same, we maintain the current speed to stay even (0)
-If the distance to the back car is greater than the one to the front, we need to slow down (-1)
-If the distance to the back car is smaller than the one to the front, we need to speed up (1)
