LeetCode—median-of-two-sorted-arrays(两个有序数组的中位数)—java 技术标签: 数组题目描述:There are two sorted arrays A and B 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))....
There are two sorted arrays A and B 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)). 说白了就是在两个有序数组,找中位数。 使用两个指针指向两个数组的起始位置,根据指针所指的数字大小,确定增加哪个指针,直到...

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)). 有两个有序数组nums1和nums2,他们的大小各是m和n,请找出这两个数组所有数的中位数,总得时间复杂度不超过O(log(m...
Median of Two Sorted Arrays(二分) LeetCode - 4. Median of Two Sorted Arrays(二分) 题目链接 题目 解析 假设两个数组的中间位置为k,其中k=(n1 + n2 + 1)/2,只要找到中间位置这个值,也就找到了中位数,所以我们可以把问题转换成查找两个数组中第 k 大的数。 如果是总数是偶数,那么如下图,我们...
There are two sorted arrays A and B 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)). 不知道是5星难度的题目,一开始做太小看他了,但在思考了近1个小时候开始着手google,然后发现网上solution各有千秋,不过发现一...
问题描述:There are two sorted arrays A and B 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)). 思路: 1. 在2个有序的数组中找中值,那么可以把2个数组合并,然后直接去中值就可以,时间复杂度为O(m+n)/2。因为...
Java: Approach 1: Recursive Approach To solve this problem, we need to understand "What is the use of median". In statistics, the median is used for: Dividing a set into two equal length subsets, that one subset is always greater than the other. ...
Can you solve this real interview question? Median of Two Sorted Arrays - Given two sorted arrays nums1 and nums2 of size m and n respectively, return the median of the two sorted arrays. The overall run time complexity should be O(log (m+n)). Examp
