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)). time=378ms accepted <pre name="code" class="j…

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 =…

题目Median of Two Sorted Arrays(难度Hard) 方案1,数组合并&排序调用Java方法 import java.util.* class Solution { fun findMedianSortedArrays(nums1: IntArray, nums2: IntArray): Double { val lenNums1 = nums1.size val lenNums2 = nums2.size val array = Arrays.copyOf(nums1,…

一.题目 Median of Two Sorted Arrays,具体请自行搜索. 这个题目,我看了一下,经过一番思考,我觉得实现起来不是很复杂. 但要做到bug free也不难,最大的问题是性能问题. 性能只有42%的样子,内存占用太多.还需要进一步优化!!! 二.这个题目,我自己实现 提交了2次: 第1次: Wrong Answer 第2次:终于对了 下面是我的完整代码实现,需要的拿去: #include<iostream> #include<vector> using nam…

题目难度:hard 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: n…

这道题是LeetCode上的题目,难度级别为5,刚开始做没有找到好的思路,以为是自己智商比较低,后来发现确实也比较低... 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: n…

题目难度:Medium Given n non-negative integers a1, a2, ..., an, where each represents a point at coordinate (i, ai). n vertical lines are drawn such that the two endpoints of line i is at (i, ai) and (i, 0). Find two lines, which together with x-axis form…

题目难度:Medium 题目: Given an array S of n integers, are there elements a, b, c, and d in S such that a + b + c + d = target? Find all unique quadruplets in the array which gives the sum of target. Note: The solution set must not contain duplicate quadrup…

题目: Given an array of integers, return indices of the two numbers such that they add up to a specific target. You may assume that each input would have exactly one solution, and you may not use the same element twice. 翻译: 给定一组整数,两个数字的返回索引,它们的和会等于一个特定…

题目:求所有全排列 难度:Medium 题目内容: Given a collection of distinct integers, return all possible permutations. 翻译:给定一组各不相同的整数,返回所有可能的排列. Example: Input: [1,2,3] Output: [ [1,2,3], [1,3,2], [2,1,3], [2,3,1], [3,1,2], [3,2,1] ] 我的思路:每种情况中,每一个元素只出现一次,只是之间的顺序不同,那么…
