Given two sorted arraysnums1andnums2of sizemandnrespectively, returnthe medianof the two sorted arrays. The overall run time complexity should beO(log (m+n)). Example 1: Input: nums1 = [1,3], nums2 = [2] Output: 2.00000 Explanation: merged array = [1,2,3] and median is 2. Exa...
Related Topic: Array, Binary Search, Divide and Conquer 解题思路:通过分治法来削减题目的规模,需要分别处理总数为奇数或偶数的情况,将题目转化为求数组的第k个元素。递归的退出条件为:1.若当前index超出当前数组的长度,则从另一个数组中去求kth元素。2.若已经递归到最底层,k=1的情况,取两个数组中较小的值。
Median of Two Sorted Arrays 解题方法 基本思路是把两个数组合并,做一个排序,然后从中取出中位数即可。 采用递归的方法可以将时间复杂度降低到O(log(min(m,n))),难度过大不研究了。 代码 # Python class Solution: def findMedianSortedArrays(self, nums1: List[int], nums2: List[int]) -> float: f...
int sumOfLength = m+n; boolean isSumOfLengthOdd = true; int medianIndex = 0; if(sumOfLength%2==0){ isSumOfLengthOdd = false; medianIndex = sumOfLength/2; }else{ medianIndex = (sumOfLength+1)/2; } if(nums1==null || m==0){ return getMedianOfArray(nums2,isSumOfLengthOdd,...
