Median of Two Sorted Arrays 解答

Question 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)). Solution 1 -- Traverse Array Use merge procedure of merge sort here.…

【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…

[LintCode] Median of Two Sorted Arrays 两个有序数组的中位数

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…

2.Median of Two Sorted Arrays (两个排序数组的中位数)

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…

【转载】两个排序数组的中位数 / 第K大元素（Median of Two Sorted Arrays）

转自 http://blog.csdn.net/zxzxy1988/article/details/8587244 给定两个已经排序好的数组(可能为空),找到两者所有元素中第k大的元素.另外一种更加具体的形式是,找到所有元素的中位数.本篇文章我们只讨论更加一般性的问题:如何找到两个数组中第k大的元素?不过,测试是用的两个数组的中位数的题目,Leetcode第4题 Median of Two Sorted Arrays方案1:假设两个数组总共有n个元素,那么显然我们有用O(n)时间和O(n)空间的…
