Kth Largest Element in an Array Problem Statement Given an integer array nums and an integer k, return the kth largest element in the array. Note that it is the kth largest element in the sorted order, not the kth distinct element. Input Specification The input consists of two parts: 1. An integer array nums. 2. An integer k. Output Specification Return a single integer, the kth largest element. Constraints 1 <= k <= nums.length <= 10^5 10^4 <= nums[i] <= 10^4 Sample Test Cases Sample Input 1 Sample Output 1 Explanation 1 Sorted array in descending order: [6,5,4,3,2,1]. The 2nd largest element is 5. Sample Input 2 Sample Output 2 Explanation 2 Sorted array in descending order: [6,5,5,4,3,3,2,2,1]. The 4th largest element is 4. Difficulty Level Medium
