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)). 解法一:保底做法,O(m+n)复杂度 按照归并排序的思路,先归并,再找中间值
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,我们的中位数肯定是(Ck-1 + CK) / 2;而...
