Top K Frequent Element ​
Top K Frequent Element — LeetCode
Given an integer array nums and an integer k, return the k most frequently occurring elements.
Approach ​
I was on the right track by first counting the numbers, then making a table with the indices being the count and the value being the List of numbers matching the count. Then just reading the table in reverse till K is reached.
Remarks ​
I really struggled with Arrays and Lists in C#
