两排序好的数组,找中位数 描述There are two sorted arrays A and B of size m and n respectively. Find the median of the two sortedarrays. The overall run time complexity should be O(log(m + n)).分析这是一道非常经典的题.这题更通用的形式是,给定两个已经排序好的数组,找到两者所有元素中第 k 大的元素.O(m + n) 的解法比较直观,直…

难度系数:5星 /*************************************************************************** 题目:有两个排好序的数组,要求其中位数,时间复杂度控制在O(log(m+n)) 一般化:求两个排序数组的第K大的元素 直观思路1:PA和PB首先指向这两个子数组,对比比较,A小则PA++,m++,B小则 PB++,m++,直至m==k ======>> 时间复杂度O(m+n) 正解思路: 由于数组是有序的,又是有序的,能否通过…

4. Median of Two Sorted Arrays 题目 There are two sorted arrays nums1 and nums2 of size m and n respectively. Find the median of the two sorted arrays. The overall run time complexity should be O(log (m+n)). Example 1: nums1 = [1, 3] nums2 = [2] The me…

一道非常经典的题目,Median of Two Sorted Arrays.(PS:leetcode 我已经做了 190 道,欢迎围观全部题解 https://github.com/hanzichi/leetcode) 题意非常简单,给定两个有序的数组,求中位数,难度系数给的是 Hard,希望的复杂度是 log 级别.回顾下中位数,对于一个有序数组,如果数组长度是奇数,那么中位数就是中间那个值,如果长度是偶数,就是中间两个数的平均数. O(nlogn) 最容易想到的解法是 O(nlogn) 的解…
