LeetCode 4 Median of Two Sorted Array

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)). 这个题是求两个已排数组的中位数,更一般的就是求两个已排数组的第k大的数. 自己想到的解决方法有一个先用合并排序将两个数组进行排序得到一个排列后的数组,在遍历找到第k到的数…

【算法之美】求解两个有序数组的中位数 — leetcode 4. Median of Two Sorted Arrays

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…
