my solution: function order(words){ var splitToArr = words.split(' '), len = splitToArr.length, newArr = [], newWords = ""; if (!len) { return words; } else { for (var i = 0; i < len; i++) { var replaceToNum = splitToArr[i].replace(/[^1-9]/ig…
从string[]转List<string>: " }; List<string> list = new List<string>(str); 从List<string>转string[]: List<string> list = new List<string>(); string[] str = list.ToArray(); Array类实现了数组中元素的冒泡排序.Sort()方法要求数组中的元素实现IComparab…
Given a sorting order string, sort the input string based on the given sorting order string. Ex sorting order string -> dfbcae Input string -> abcdeeabc output -> dbbccaaee 法一:Comparable sample Input: String order = "dfbcae"; String str…
题目: Given a string s1, we may represent it as a binary tree by partitioning it to two non-empty substrings recursively. Below is one possible representation of s1 = "great": great / \ gr eat / \ / \ g r e at / \ a t To scramble the string, we ma…
To some string S, we will perform some replacement operations that replace groups of letters with new ones (not necessarily the same size). Each replacement operation has 3parameters: a starting index i, a source word x and a target word y. The rule…
Bucket Sort is a sorting method that subdivides the given data into various buckets depending on certain characteristic order, thuspartially sorting them in the first go.Then depending on the number of entities in each bucket, it employs either bucke…

这个类在日常的开发中,还是非常常用的.今天就总结一下Arrays工具类的常用方法.最常用的就是asList,sort,toStream,equals,copyOf了.另外可以深入学习下Arrays的排序算法,这个还是非常有用的. 所有的方法都是在下面的类中进行测试的: public class ArraysTest { String[] array = new String[]{"a","c","2","1","b&…
系列目录 我们之前做了验证码,登录界面,却没有登录实际的代码,我们这次先把用户登录先完成了,要不权限是讲不下去了 把我们之前的表更新到EF中去 登录在Account控制器,所以我们要添加Account的Model,BLL,DAL AccountModel我们已经创建好了,下面是DAL和BLL的类 using System; using System.Collections.Generic; using System.Linq; using System.Text; using App.Model…
