6、快速排序(Quick Sort) 快速排序的基本思想:通过一趟排序将待排记录分隔成独立的两部分,其中一部分记录的关键字均比另一部分的关键字小,则可分别对这两部分记录继续进行排序,以达到整个序列有序。 6.1 算法描述 快速排序使用分治法来把一个串(list)分为两个子串(sub-lists)。具体算法描述如下: 从数列中挑出一...
util.Arrays; public class Solution { // 选择排序:每一轮选择最小元素交换到未排定部分的开头 public int[] sortArray(int[] nums) { int len = nums.length; // 循环不变量:[0, i) 有序,且该区间里所有元素就是最终排定的样子 for (int i = 0; i < len - 1; i++) { // 选择区间 [...

从2020年十一月份开始,陆陆续续开始刷LeetCode,到今天(2021年4月9日)终于刷到了三百题。因为三个原因自己想在LeetCode300题时做个小结整理一下,一方面以前听人说LeetCode刷个三百基本就可以找工作了,后来又看见有人说自己LeetCode300题左右进入了瓶颈期,怎么刷都提升不大。还有一个方面,因为属于天赋极差的学生,...
// Solution 1: To minimize the maximum, these sort of problems are widely studied in computer science. Isn't there something called "Minimax" in Decision Thoery, for instance? As this problem is about splitting subarrays, we can do it with DP. Say, if the problem is about partitioning ...
