75. 颜色分类 75. Sort Colors 题目描述 给定一个包含红色.白色和蓝色,一共 n 个元素的数组,原地对它们进行排序,使得相同颜色的元素相邻,并按照红色.白色.蓝色顺序排列. 此题中,我们使用整数 0. 1 和 2 分别表示红色.白色和蓝色. 注意: 不能使用代码库中的排序函数来解决这道题. 每日一算法2019/6/2Day 30LeetCode75. Sort Colors 示例: 输入: [2,0,2,1,1,0] 输出: [0,0,1,1,2,2] 进阶: 一个直观的解决方…
Given an array with n objects colored red, white or blue, sort them so that objects of the same color are adjacent, with the colors in the order red, white and blue. Here, we will use the integers 0, 1, and 2 to represent the color red, white, and bl…

给定一个包含红色.白色和蓝色,且含有 n 个元素的数组,对它们进行排序,使得相同颜色的元素相邻,颜色顺序为红色.白色.蓝色.此题中,我们使用整数 0, 1 和 2 分别表示红色,白色和蓝色.注意:不能使用代码库中的排序函数来解决这道题.进阶:一个相当直观的解决方案是使用计数排序的 two-pass 算法.首先,迭代计算出0,1 和 2 元素的个数,然后重写当前数组.你能想出一个仅使用恒定空间的 one-pass 算法吗?详见:https://leetcode.com/problems/sort-…

1. 排序 排序(sort)是一种常见的算法,把数据根据特定的顺序进行排列.经典的排序算法如下: 冒泡排序(bubble sort) 插入排序(insertion sort) 选择排序(selection sort) 快速排序(quick sort) 堆排序(heap sort) 归并排序(merge sort) 冒泡排序依次比较相邻的两个元素,若逆序则交换:如此走访数列重复n次,即不再发生交换,排序完成.(以下图片均来自于Wikipedia) 但是,冒泡排序存在着许多无意义的交换,比如:对于基…
