LintCode 508: Wiggle Sort 题目描述 给你一个没有排序的数组,请将原数组就地重新排列满足如下性质 nums[0] <= nums[1] >= nums[2] <= nums[3].... Thu Feb 23 2017 思路 这道题看起来好像无从下手,但其实思路很简单,方法也有很多种. 第一种方法 先将数组排序,然后将第二个.第三个数交换,第四个.第五个数交换...即可.时间复杂度是\(O(nlogn)\). 第二种方法 第二种方法先找出数字们的中位数,然后将大于…

一. 题目描写叙述 Given an unsorted array nums, reorder it in-place such that nums[0] <= nums[1] >= nums[2] <= nums[3]- For example, given nums = [3, 5, 2, 1, 6, 4], one possible answer is [1, 6, 2, 5, 3, 4]. 二. 题目分析 题目给出一个未排序的数组,调整元素的大小使其满足nums[0] <=…

Given an unsorted array nums, reorder it in-place such that nums[0] <= nums[1] >= nums[2] <= nums[3].... For example, given nums = [3, 5, 2, 1, 6, 4], one possible answer is [1, 6, 2, 5, 3, 4]. 这道题让我们求摆动排序,跟Wiggle Sort II相比起来,这道题的条件宽松很多,只因为多了一个等号…

Given an unsorted array nums, reorder it such that nums[0] < nums[1] > nums[2] < nums[3].... Notice You may assume all input has valid answer. ExampleGiven nums = [1, 5, 1, 1, 6, 4], one possible answer is [1, 4, 1, 5, 1, 6]. Given nums = [1, 3,…
