    C++ XML is a book exclusively devoted to the pow er and complexities of integrating XML standards into C++. As a developer,this is a book you cannot miss. C++ XML addresses all major standards,toolkits,and types of applications dealing with XML as a format for representing and exchanging data,as well as XML behavior,from a C++ standpoint. It explains the implementation of applications and reusuable frameworks for all major XML purposes exclusively using C/C++ parsers and toolkits, such as expat,Xerces,Xalan,libxml2,and Microsoft’s MSXML.

    The i-mode service by NTT DoCoMo is a mobile phone service in Japan that provides its customers with both voice and comprehensive data services. With an i-mode phone, users can exchange i-mode e-mail and obtain information from i-mode menu sites and i-mode compatible Internet sites. The i-mode phone contains a browser that displays i-mode compatible HTML web pages. Beginning with the 505i phones, you can view Macromedia Flash Lite movies from the i-mode browser. You can also use the phones’ My Picture and Standby Screen applications to view Flash Lite movies. Although a number of manufacturers produce 505i phones, all of them support the same Flash Lite functionality.

  • 【问题描述】 在一个N*N的点阵中

    【问题描述】 在一个N*N的点阵中,如N=4,你现在站在(1,1),出口在(4,4)。你可以通过上、下、左、右四种移动方法,在迷宫内行走,但是同一个位置不可以访问两次,亦不可以越界。表格最上面的一行加黑数字A[1..4]分别表示迷宫第I列中需要访问并仅可以访问的格子数。右边一行加下划线数字B[1..4]则表示迷宫第I行需要访问并仅可以访问的格子数。如图中带括号红色数字就是一条符合条件的路线。 给定N,A[1..N] B[1..N]。输出一条符合条件的路线,若无解,输出NO ANSWER。(使用U,D,L,R分别表示上、下、左、右。) 2 2 1 2 (4,4) 1 (2,3) (3,3) (4,3) 3 (1,2) (2,2) 2 (1,1) 1 【输入格式】 第一行是数m (n < 6 )。第二行有n个数,表示a[1]..a[n]。第三行有n个数,表示b[1]..b[n]。 【输出格式】 仅有一行。若有解则输出一条可行路线,否则输出“NO ANSWER”。
