Given 2 elevators (named "left" and "right") in a building with 3 floors (numbered 0
to 2
), write a function accepting 3 arguments (in
order):
left
- The current floor of the left elevatorright
- The current floor of the right elevatorcall
- The floor that called an elevator
It should return the name of the elevator closest to the called floor ("left"
/"right"
).
In the case where both elevators are equally distant from the called floor, choose the elevator to the right.
You can assume that the inputs will always be valid integers between 0-2.
Examples:
left right call result
0 1 0 "left"
0 1 1 "right"
0 1 2 "right"
0 0 0 "right"
0 2 1 "right"
