问题
若二维数组arr[1..M,1..N]的首地址为base,数组元素按列存储且每个元素占用K个存储单元,则元素arr[i,j]在该数组空间的地址为()。A、base+((i-1)*M+j-1)*KB、base+((i-1)*N+j-1)*KC、base+((j-1)*M+i-1)*KD、base+((j-1)*N+i-1)*K
问题
在有n个无序无重复元素值的数组中查找第i小的数的算法描述如下:任意取一个元素r,用划分操作确定其在数组中的位置,假设元素r为第k小的数。若i等于k,则返回该元素值;若i小于k,则在划分的前半部分递归进行划分操作找第i小的数;否则在划分的后半部分递归进行划分操作找第k-i小的数。该算法是一种基于()策略的算法。A、分治B、动态规划C、贪心D、回溯
问题
一组对象以定义良好但是复杂的方式进行通信,产生的相互依赖关系结构混乱且难以理解。采用()模式,用一个中介对象来封装一系列的对象交互,从而使各对象不需要显式地相互引用,使其耦合松散,。而且可以独立地改变它们之间的交互。此模式与()模式是相互竞争的模式,主要差别是:前者的中介对象封装了其它对象间的通信,而后者通过引入其它对象来分布通信。A、解释器(Interpreter)B、策略(Strategy)C、中介者(Mediator)D、观察者(Observer)

Extreme Programming (XP) is a discipline of sofiware development with (1) of simplicity,communication, feedback and cuurage. Successful software development is a team effort - not just the development team, but the larger team consisting of customer, management and developers. XP is a simple process that brings these people together and helps them to success together. XP is aimed primarily at object-oriented projects using teams of a dozen or fewer programmers in one location. The principles of XP apply to any (2) project that needs to deliver quality software rapidly and flexibly. An XP project needs a (3) customer to provide guidance. Customers, programmers, managers, are all working (4) to build the system that's needed, Customers - those who have software that needs to be developed - will learn simple, effective way to (5) what they need, to be sure that they are getting what they need, and to steer the project to success.
空白(2)处应选择()A、small-sizedB、moderately-sizedC、large-sizedD、huge-sized

Ravi, like many project (1) , had studied the waterfall model of software development as the primary software life-cycle (2) . He has all set to use it for an upcoming project, his first assignment. However, Ravi found that the waterfall model could not be used because the customer wanted the software delivered in stages, something that implied that the system had to be delivered and built in (3) and not as (4) . The situation in many other projects is not very different. The real world rarely presents a problem in which a standard process, or the process used in a previous project, is the best choice. To be the most situation, an existing process must be (5) to the new problem. A development process, even after tailoring, generally cannot handle change requests. To accommodate change requests without losing control of the project, you must supplement the development process with a requirement change management process.
