Solution: Kth Largest Element in an Array

Understand how to find the kth largest element in an unsorted array by implementing a min heap to keep track of the largest elements. This lesson helps you avoid full sorting, optimize performance with heap operations, and calculate time and space complexities effectively.

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 ...
