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)). public class Solution { public double findMedianSortedArrays(int A[], int B[]) { int k…

Median of Two Sorted Arrays 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)).SOLTION 1: 1. 我们借用findKthNumber的思想.先实现findKthNumber,如果是偶数个,…

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)). 这道题让我们求两个有序数组的中位数,而且限制了时间复杂度为O(log (m+n)),看到这个时间复杂度,自然而然的想到了应该使用二分查找法来求解.但是这道题…

Description: 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)). 思路:找出两个已经排好序数组的中位数.可以使用合并排序中的merge,然后直接找出中位数就能AC.时间复杂度为O(m+n).但是!…

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)). 将两个有序数组合并,注意题目求得是the median of the two sorted array, 当m+n是奇数时返回的是合并后的中间数即C[(m+n)/2] 当m…

坚持每天刷一道题的小可爱还没有疯,依旧很可爱! 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)). Example 1: nums1 = [1, 3],nums2 = [2], The median is…

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)). Example 1: nums1 = [1, 3] nums2 = [2] The median is 2.0 Example 2: nu…

求2个数组的中位数 方法很多 但是时间复杂度各异 1利用数组copy方法先融合两个数组,然后排序,找出中位数 import java.lang.reflect.Array; import java.util.Arrays; import java.util.Collection; import java.util.Collections; public class _004MedianofTwoSortedArrays { public static void main(String[] arg…

这个问题的大意是提供两个有序的整数数组A与B,A与B并集的中间数.[1,3]与[2]的中间数为2,因为2能将A与B交集均分.而[1,3]与[2,4]的中间数为2.5,取2与3的平均值.故偶数数目的中间值与奇数数目的中间值的算法不同.这个问题要求时间复杂度不超过O(log(n+m)),其中n与m分别为A与B的长度. 对于这个问题,我一开始的想法是同时对两个集合用二分查找法,这样每次过程都能有效减少一部分的冗余数据,且这样的算法的时间复杂度为O(log(n)+log(m))=O(log(max(n,…
