| Write a method mode which takes an Array of numbers | |
| as its input and returns an Array of the most frequent values. | |
| If there's only one most-frequent value, it returns a | |
| single-element Array. | |
| For example, | |
| mode([1,2,3,3]) # => [3] | |
| mode([4.5, 0, 0]) # => [0] |
| Create an RPNCalculator class which can evaluate expressions | |
| written in Reverse Polish notation. | |
| It should have an evaluate instance method which takes as its | |
| input a valid RPN expression and returns its evaluation. Your | |
| calculator only needs to handle addition, multiplication, and | |
| subtraction (not division). | |
| Operators and numbers should be separated by a single space. |
