Top K Elements in List

Comment

/*
	Given an integer array nums and an integer k, return the k most frequent 
    elements within the array.

	The test cases are generated such that the answer is always unique.
    Example 1:
    Input: nums = [1,2,2,3,3,3], k = 2
    Output: [2,3]
    
    Example 2:
    Input: nums = [7,7], k = 1
    Output: [7]

    // then slice sorted array by number of (k), then reverse array
