解题思路:合并两个数组,创建一个 Map对象,用以存放排好顺序的键值对,键为序号,值为数组值,中位数的结果分两种情况讨论: 1.m+n为奇数:(m+n)/2为中位数 2.m+n为偶数:(((m+n)/2-1)+(m+n)/2)/2为中位数 public class FindMedianNum { public static void main(String[] args) { int[] a = {1,2,3,4,5,10}; int[] b = {3,5,6,7}; double median…

题目描述: 给定两个有序整数数组 nums1 和 nums2,将 nums2 合并到 nums1 中,使得 num1 成为一个有序数组. 说明:初始化 nums1 和 nums2 的元素数量分别为 m 和 n.你可以假设 nums1 有足够的空间(空间大小大于或等于 m + n)来保存 nums2 中的元素. 示例: 输入: nums1 = [1,2,3,0,0,0], m = 3 nums2 = [2,5,6], n = 3 输出: [1,2,2,3,5,6] 代码如下: public sta…

class Solution { public double findMedianSortedArrays(int[] A, int[] B) { int m = A.length; int n = B.length; if (m > n) { // to ensure m<=n int[] temp = A; A = B; B = temp; int tmp = m; m = n; n = tmp; } int iMin = 0, iMax = m, halfLen = (m + n + 1…

问题: 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)). Example1:nums1 = [1, 3]nums2 = [2]The median is 2.0Example2:nums1 = [1, 2]n…

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…
