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 elevator
• right - The current floor of the right elevator
• call - 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"
