Solution: Kth Largest Element in an Array

Explore how to determine the kth largest element in an array efficiently by using the top k elements pattern with a min heap. Learn to avoid full sorting by maintaining a heap of size k, improving time performance. Understand the algorithm implementation and analyze its time and space complexities to prepare for interview problems involving selection and heaps.

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 ...
