LeetCode OJ 4. Median of Two Sorted Arrays

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 median is 2.0

Example 2:

nums1 = [1, 2]
nums2 = [3, 4]

The median is (2 + 3)/2 = 2.5

Leetcode Array 4 Median of Two Sorted Arrays

做leetcode题目的第二天,我是按照分类来做的,做的第一类是Array类,碰见的第二道题目,也就是今天做的这个,题目难度为hard.题目不难理解,但是要求到了时间复杂度,就需要好好考虑使用一下算法了.刚开始没啥思路,就用暴力的方法,用双层循环遍历的一下两个已经排好序的数组 ,在中间位置停止找道中位数.这样时间复杂度是肯定不能满足题目要求的,但是程序测试还是过了. 苦于自己没有思路,又不甘心就这样水过一道题,还是搜了一下博客,膜拜了一下大神.最好的方法是将中位数  -- 两个数组数据排好序之后

LeetCode(4) － Median of Two Sorted Arrays

题目要求很简单,就是给你两个已经排好序的数组nums1(长度为m)和nums2(长度为n),找出他们的中间值.返回值类型double是因为如果数字个数是偶数个,就要返回中间两个数的平均值.这题最简单的方法就是通过两个指针分别从nums1和nums2的头一直移动,直到走到nums1和nums2的中值位置为止.整个过程耗时大概是O((m+n) / 2).但是题目附带需要用O(log(m+n))的时间完成,所以上述方法就不能用了.能用到O(log(m+n))的方法在leetcode的算法题里面没有几个
