Can you solve this real interview question? Kth Largest Element in an Array - 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 el
LeetCode 215. Kth Largest Element in an Array(排序) 题目 题意:找到一个数组里第K大的数字。 题解:我们当然可以排序好了,之后,选择第K大的数字。但是这样做一点技术含量也没有。 AI检测代码解析 排序算法选用快排。寻找第K大的数字,不必把数组完全排完序之后,再找第K大。快排中是选取一个...
LeetCode: 215. Kth Largest Element in an Array 题目描述 Find 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. ...
一、问题描述 Find 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:
Find 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. For example, Given [3,2,1,5,6,4] and k = 2, return 5. Note: You may assume k is always valid, 1 ≤ k ≤ array's length. ...
