Algorithms and Data Structures – ReversedInt
--- Directions
Given an integer, return an integer that is the reverse
ordering of numbers.
--- Examples
reverseInt(15) === 51
reverseInt(981) === 189
reverseInt(500) === 5
reverseInt(-15) === -51
reverseInt(-90) === -9
Solution
Hint: Try to use Math.sign(n) -> when it get a negative value, it will return -1, otherwise it will return 1 or 0
