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 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…

For this problem we need to sort the array into three parts namely with three numbers standing for three different colors. Currently, the method in mind could be statistically get all the frequency of three numbers by screening the whole list. Howeve…

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,…

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…

Sort ColorsGiven 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, wh…

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…

排颜色 II 给定一个有n个对象(包括k种不同的颜色,并按照1到k进行编号)的数组,将对象进行分类使相同颜色的对象相邻,并按照1,2,...k的顺序进行排序. 样例 给出colors=[3, 2, 2, 1, 4],k=4, 你的代码应该在原地操作使得数组变成[1, 2, 2, 3, 4] 解题 直接快排 class Solution { /** * @param colors: A list of integer * @param k: An integer * @return: nothin…

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…
