WebFeb 12, 2024 · Insert the first k elements of the list into the heap For each remaining element i in the list: let M be the maximum element in the heap If i < M, then delete M and insert i into the heap At the end, the heap will contain the k smallest elements in the list. Looking up the maximum element has constant cost. WebFind the kth largest element in an unsorted array. Note that it is the kth largest element in the sorted order, not the kth distinct element. Example 1: Input: [3,2,1,5,6,4] and k = 2 Output: 5 Example 2: Input: [3,2,3,1,2,4,5,5,6] and k = 4 Output: 4 Note: You may assume k is always valid, 1 ≤ k ≤ array's length.
