Solution: Top K Frequent Elements

Explore techniques to find the top K frequent elements in an array by building a frequency map and using a min heap to maintain the most frequent elements. Understand how to optimize the solution for time and space complexity and apply these concepts to improve coding interview performance.

We'll cover the following...

Statement

Given an array of integers, arr, and an integer, k, return the kk most frequent elements.

Note: You can return the answer in any order.

Constraints:

  • 11 ≤\leq arr.length ≤\leq 10310^{3}
  • −10−4-10^{-4} ≤\leq arr[i] ≤\leq 10410^{4}
