Summary
Build a method that can identify whether a number(s) is odd or even.
Exercise Description
Define a method that, when expecting an even number, will return true if an even number is passed to it and will return false if an odd number is passed to it. The method should also be able to return true/false when expecting odd numbers.
Example Data
> Even? 10 -> true 0 -> true 74834 -> true 1 -> false 101 -> false 74835 -> false > Odd? 11 -> true 77 -> true 74833 -> true 0 -> false 404 -> false 4838 -> false
Real World Usage
This coding exercise breaks down and helps you understand how to implement a method that can, first, recognize if you are looking for a odd or an even number and second, will tell you whether a certain number(s) is, in fact, an odd or an even number.
