Given a non-empty array of integers, find the top k elements which have the highest frequency in the array. If two numbers have the same frequency then the larger number should be given preference.
Example 1:
Input:
nums = {1,1,1,2,2,3},
k = 2
Output: {1, 2}
Example 2:
Input:
nums = {1,1,2,2,3,3,3,4},
k = 2
Output: {3, 2}
Explanation: Elements 1 and 2 have the
same frequency ie. 2. Therefore, in this
case, the answer includes the element 2
as 2 > 1.
User Task:
The task is to complete the function topK() that takes the array and integer k as input and returns a list of top k frequent elements.
