引到值，因此无法在链表上进行二分查找首先要求数据是有序的,同时要求能随机访问数据元素, 有序数组可以, 链表不行,二分查找因为每次都是从中间点开始查找，所以最坏情况是目标元素存在于最边缘的情况。最坏为O（LogN）7. The following is a description of the inheritance of the class, right? BA．一个类可以直接继承多个父类B．一个类可以具有多个子类C．子类会自动拥有父类定义的有效访问权限的方法以及成员变量D．一个类继承另一个类必须重写父类的方法8. What are the following description errors? (B D)A．类只能继承一个父类，但是可以实现多个接口B．抽象类自身可以定义成员而接口不可以C．抽象类和接口都不能被实例化D．一个类可以有多个基类和多个基接口Java不支持多继承，只能有一个基类接口中定义的成员变量默认为public static final，只能够有静态的不能被修改的数据成员；而且，必须给你赋初值，其所有成员方法都是public、abstract的，而且只能被这两个关键

aspects of things. Imagine, for example, a SaaS operator who wants to provide its users with service monitoring pages (for example, status pages on GitHub). With the event loop of node. js, we can create a powerful Web-based dashboard that asynchronously checks the status of the service and uses the WebSockets to push the data to the client.This technology enables real-time escalation of internal (intra-company) and public service status. Let's take this idea a little farther, and try to imagin

region Network Operation Center (NOC) or data center. Scalable and easy to upgrade Compared with access point-based wireless LAN, it is more convenient to add capacity and new features, and the cost is lower. With WS2000, your wireless switch network can be expanded as the company grows. Each WS2000 supports up to 6 access ports and 3 wireless LAN, each of which has its own security and network policies. In addition, with the centralized architecture
