    DirectX not only provides fast access to the hardware and therefore incredibly speedy performance, but it also makes it much easier for hardware developers to produce new devices that work well in the Windows environment. The DirectX APIs take away the necessity of writing your own low-level, device-specific code to access hardware such as the display adapter and network card, making it much easier for you to write programs that take full advantage of the computer s multimedia capabilities.

    数据结构 1、算法思路: 哈夫曼树算法:a)根据给定的n个权值{W1,W2… ,Wn }构成 n棵二叉树的集合F={T1,T2…,T n },其中每棵二叉树T中只有一个带权为W i的根结点,其左右子树均空;b)在F中选取两棵根结点的权值最小的树作为左右子树构造一棵新的二叉树,且置新的二叉树的根结点的权值为其左、右子树上结点的权值之和;c)F中删除这两棵树,同时将新得到的二叉树加入F中; d)重复b)和c),直到F只含一棵树为止。

    Swfdec still is development software, but has also followed a rigid no-crashes-allowed policy. I believe it s stable enough now to be installed as a default plugin for people that can live with occasional crashes of their browser. But don t blame me if it does crash. File a bug at https://bugs.freedesktop.org/enter_bug.cgi?product=swfdec

    1) Write a function reverse(A) which takes a matrix A of arbitrary dimensions as input and returns a matrix B consisting of the columns of A in reverse order. Thus for example, if A = 1 2 3 then B = 3 2 1 4 5 6 6 5 4 7 8 9 9 8 7 Write a main program to call reverse(A) for the matrix A = magic(5). Print to the screen both A and reverse(A). 2) Write a program which accepts an input k from the keyboard, and which prints out the smallest fibonacci number that is at least as large as k. The program should also print out its position in the fibonacci sequence. Here is a sample of input and output: Enter k>0: 100 144 is the smallest fibonacci number greater than or equal to 100. It is the 12th fibonacci number.

  • 基于J2EE的物流信息系统的设计与实现 介绍了J2EE 体系结构、Mv c模式等相关概念和技术

    基于J2EE的物流信息系统的设计与实现 介绍了J2EE 体系结构、Mv c模式等相关概念和技术,并重点探讨了 目 前比 较受欢迎的三种开源框架( s t r ut s框架、S Pr i n g框架和H i b e m a t e 框架)。 分析了他们的体系结构、 特点和优缺点。 根据J ZE E的分层结构,结合We b应用 的特点, 将三种框架进行组合设计, 即表现层用S t r ut s框架、 业务逻辑层用S P ri n g 框架、持久层用比b ema t e 框架,从而来构建物流信息系统。这种整合框架使各 层相对独立, 减少各层之间的祸合程度,同时加快了系统的开发过程,增强了系 统的可维护性和可扩展性,初步达到了分布式物流信息系统的设计目标。 经过以上分析,结合物流系统的业务需求,进行了相关的实现。最后,系统 运用先进的A ja x技术来增强Ui层与服务器的异步通信能力, 使用户体验到动态 且响应灵 敏的桌 面级w e b应用程序。 通过江联公司的试运行结果,系统达到了 渝眯。 并 且 对 江 联 公 司 提 出 了 基 于 R F I D 的 解 决 方 案 的 实 施 计 划 。

  • 设平面上分布着n个白点和n个黑点

    设平面上分布着n个白点和n个黑点,每个点用一对坐标(x, y)表示。一个黑点b=(xb,yb)支配一个白点w=(xw, yw)当且仅当xb>=xw和yb>=yw。若黑点b支配白点w,则黑点b和白点w可匹配(可形成一个匹配对)。在一个黑点最多只能与一个白点匹配,一个白点最多只能与一个黑点匹配的前提下,求n个白点和n个黑点的最大匹配对数。
