[Leetcode]215. Kth Largest Element in an Array 这是Leetcode第215题,求无序数组第K大的数。 求第K大/小的数也是一个经典的问题了,一般来说有两种方法:堆思想和快排思想。其时间复杂度分别达到O(NlogK)O(NlogK)和O(N)O(N)。我们先分析这两种算法,然后分析一个优化算法。 堆 一般来说,求第K大数使...

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:
今天介绍的是LeetCode算法题中Easy级别的第164题(顺位题号是703)。设计一个类来查找流中第k个最大元素。请注意,它是排序顺序中的第k个最大元素,而不是第k个不同元素。KthLargest类有一个构造方法,此构造方法有一个整数k和一个整数数组nums两个参数,它包含来自流的初始元素。对于方法KthLargest.add的每次调用...
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. ...
