Return Two Highest Values in List

Description

In this kata, your job is to return the two distinct highest values in a list. If there're less than 2 unique values, return as many of them, as possible.

The result should also be ordered from highest to lowest.

Examples:

[4, 10, 10, 9]  =>  [10, 9]
[1, 1, 1]  =>  [1]
[]  =>  []

My Solution

def two_highest(list)
  list.uniq.sort.reverse[0..1]
end

Better/Alternative solution from Codewars

def two_highest list
  list.uniq.max 2
end
