Exact Change 设计一个收银程序 checkCashRegister() ,其把购买价格(price)作为第一个参数 , 付款金额 (cash)作为第二个参数, 和收银机中零钱 (cid) 作为第三个参数. cid 是一个二维数组,存着当前可用的找零. 当收银机中的钱不够找零时返回字符串 "Insufficient Funds". 如果正好则返回字符串 "Closed". 否则, 返回应找回的零钱列表,且由大到小存在二维数组中. function chec…
Finders Keepers 写一个 function,它浏览数组(第一个参数)并返回数组中第一个通过某种方法(第二个参数)验证的元素. 如果你被卡住了,记得开大招 Read-Search-Ask.尝试与他人结伴编程.编写你自己的代码. function find(arr, func) { /*方法1*/ for(var i=0; i<arr.length; i++){ if(func(arr[i])){ return arr[i]; } } /*end方法1*/ /*方法2*/ arr=ar…
Bubble sort,It's a relatively basic algorithm.The core implementation ideas are as follows: 1.Define an array,The length is N. 2.Compares each pair of adjacent items and swaps them if they are in the wrong order. such as: if (a[j - 1] > a[j]) {//The…

一.前言 本篇是在分析Executors源码时,发现JUC集合框架中的一个重要类没有分析,SynchronousQueue,该类在线程池中的作用是非常明显的,所以很有必要单独拿出来分析一番,这对于之后理解线程池有很有好处,SynchronousQueue是一种阻塞队列,其中每个插入操作必须等待另一个线程的对应移除操作 ,反之亦然.同步队列没有任何内部容量,甚至连一个队列的容量都没有. 二.SynchronousQueue数据结构 由于SynchronousQueue的支持公平策略和非公平策略,所…

最近在网上搜索Python和WMI相关资料时,发现大部分文章都千篇一律,并且基本上只说了很基础的使用,并未深入说明如何使用WMI.本文打算更进一步,让我们使用Python玩转WMI. 1 什么是WMI 具体请看微软官网对WMI的介绍.这里简单说明下,WMI的全称是Windows Management Instrumentation,即Windows管理规范.它是Windows操作系统上管理数据和操作的基础设施.我们可以使用WMI脚本或者应用自动化管理任务等. 从Using WMI可以知道WMI支…
