Given an integer array, sort it in ascending order. Use quick sort, merge sort, heap sort or any O(nlogn) algorithm. Example Given [3, 2, 1, 4, 5], return [1, 2, 3, 4, 5]. 快速排序是排序算法中比较重要一种,也是经常容易考的一种排序算法,务必要掌握好.快排的优点是其平均时间复杂度为O(nlgn),这样在给大数据集排序的时候,…
Sort Colors II 原题链接: http://lintcode.com/zh-cn/problem/sort-colors-ii/# Given an array of n objects with k different colors (numbered from 1 to k), sort them so that objects of the same color are adjacent, with the colors in the order 1, 2, ... k. 注意…
Given an integer array, sort it in ascending order. Use selection sort, bubble sort, insertion sort or any O(n2) algorithm. Example Given [3, 2, 1, 4, 5], return [1, 2, 3, 4, 5]. 这道题让我们实现最基本的几个O(n2)的排序算法,选择排序,冒泡排序和插入排序,都是最基本的排序算法.我们一个一个来看,首先来看冒泡排序,…
Given an array of n objects with k different colors (numbered from 1 to k), sort them so that objects of the same color are adjacent, with the colors in the order 1, 2, ... k. Note You are not suppose to use the library's sort function for this probl…
Given an unsorted array nums, reorder it in-place such that nums[0] <= nums[1] >= nums[2] <= nums[3].... Notice Please complete the problem in-place. Example Given nums = [3, 5, 2, 1, 6, 4], one possible answer is [1, 6, 2, 5, 3, 4]. 分析: 排序,从第三个开…
最后更新 一刷 class Solution { public void sortColors2(int[] colors, int k) { // write your code here if (colors.length <= 1) return; int start = 0; int end = colors.length - 1; int min = 1; int max = k; while (start < end) { int temp = start; while (temp…
