Solution: Kth Largest Element in an Array

Explore how to identify the kth largest element in an unsorted array by using a min heap that maintains the top k elements. Learn the algorithm to insert and remove elements efficiently to get the correct value, while understanding the time and space complexity involved in this solution.

Statement

Given an integer array, nums, and an integer, k, determine and return the kth largest element in the array.

Note: The kth largest element is defined with respect to the array’s sorted order (descending), and does not necessarily correspond to the kth unique value.

Constraints:

  • 11 \leq k \leq nums.length 103\leq 10^3

  • 104-10^4 \leq ...
