+# [Closest elevator](https://www.codewars.com/kata/closest-elevator "https://www.codewars.com/kata/5c374b346a5d0f77af500a5a")
+
+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"
+```
