题目: 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)). 题意已只两个有序的序列,找到他们的中位数,复杂度要求O(log (m+n)). 问题可以转化成两个有序序列找第num大的数,用类似二分的思想,用递归处理. 因为两个…

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)). You may assume nums1 and nums2 cannot be both empty. Example 1:       nums1 =…

题目: 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)). 题意: 两个排序后的数组nums1 和nums2,长度分别是m,n,找出其中位数,并且时间复杂度:O(log(m+n)) 最愚蠢的方法: 两个数组合…

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,…

题意: 给两个有序(升or降)的数组,求两个数组合并之后的中位数. 思路: 按照找第k大的思想,很巧妙.将问题的规模降低,对于每个子问题,k的规模至少减半. 考虑其中一个子问题,在两个有序数组中找第k大,我们的目的只是将k的规模减半而已,所以可以对比nums1[k/2]和nums2[k/2]的大小,假设nums1[k/2]<=nums2[k/2],那么nums1[0~k/2]这部分必定在0~k之中,那么将这部分删去,k减半,再递归处理.这里面可能有一些细节问题要考虑: 1. 如果其中1个数组的大…
