给定两个大小为 m 和 n 的有序数组 nums1 和 nums2 . 请找出这两个有序数组的中位数.要求算法的时间复杂度为 O(log (m+n)) . 你可以假设 nums1 和 nums2 不同时为空. 示例 1: nums1 = [1, 3] nums2 = [2] 中位数是 2.0 示例 2: nums1 = [1, 2] nums2 = [3, 4] 中位数是 (2 + 3)/2 = 2.5 bool cmp1(int x, int y) { return x < y; } clas…

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…

There are two sorted arrays A and B of size m and n respectively. Find the median of the two sorted arrays. Have you met this question in a real interview?     Example Given A=[1,2,3,4,5,6] and B=[2,3,4,5], the median is 3.5. Given A=[1,2,3] and B=[4…

要求:Median of Two Sorted Arrays (求两个排序数组的中位数) 分析:1. 两个数组含有的数字总数为偶数或奇数两种情况.2. 有数组可能为空. 解决方法: 1.排序法 时间复杂度O(m+n),空间复杂度 O(m+n) 归并排序到一个新的数组,求出中位数. 代码: class Solution { public: double findMedianSortedArrays(int A[], int m, int B[], int n) { int *C = new int…
