Web19 aug. 2024 · Problem – Kth Largest Element in an Array Given an integer array nums and an integer k, return the k th largest element in the array. Note that it is the k th largest element in the sorted order, not the k th distinct element. You must solve it in O (n) time complexity. Example 1: Input: nums = [3,2,1,5,6,4], k = 2 Output: 5 Example 2: Web11 jul. 2024 · Solution one is using sort and sort the input in descending order and the kth largest elemenet will be the k-1. Python using timesort which time complexity is O (nlogn). Second solution is general. You can build a heap from input array and pop the heap until there k element left. Building heap is taking O (nlogn) time complexity. Solution 1:
