题目描述: 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)). 解题思路: 这道题个人觉得是很难的,要想解出这个题,就必须了解一下几点: 1.求一列长度为len的数字的中位数,其实也可以被看做是求第len/2…

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 2.0 Example 2: nums1 =…

[题意] 给两个有序数组,寻找两个数组组成后的中位数,要求时间复杂度为O(log(n+m)). [题解] 感觉这道题想法非常妙!! 假定原数组为a,b,数组长度为lena,lenb. 那么中位数一定是第k = (lena + lenb + 1)/ 2小的数,如果是数组长度和是偶数的话就是第k = (lena + lenb + 1)/ 2小和第k = (lena + lenb + 2)/ 2小的数,所以我们可以把问题转化为求第k小的数. 然后分别对a,b找第k / 2小的数,假如a[k / 2 -…

一天一道LeetCode (一)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)). 给定两个排好序的数组,求两个数组的中间值. 例如:[1 2]和[1 2] 返回值:1.5 (二)解题思路 时间复杂度要…

题目如下: Given three integer arrays arr1, arr2 and arr3 sorted in strictly increasing order, return a sorted array of only the integers that appeared in all three arrays. Example 1: Input: arr1 = [1,2,3,4,5], arr2 = [1,2,5,7,9], arr3 = [1,3,4,5,8] Outpu…

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,…

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 = [1, 3]…
