This book is for you if
You re no "dummy," and you need to get quickly up to speed in intermediate to advanced C++
You ve had some experience in C++ programming, but reading intermediate and advanced C++ books is slow-going
You ve had an introductory C++ course, but you ve found that you still can t follow your colleagues when they re describing their C++ designs and code
You re an experienced C or Java programmer, but you don t yet have the experience to develop nuanced C++ code and designs
You re a C++ expert, and you re looking for an alternative to answering the same questions from your less-experienced colleagues over and over again
C++ Common Knowledge covers essential but commonly misunderstood topics in C++ programming and design while filtering out needless complexity in the discussion of each topic. What remains is a clear distillation of the essentials required for production C++ programming, presented in the author s trademark incisive, engaging style.
Given Perl s natural fit for web applications development, it s no surprise that Perl is also a natural choice for web services development. It s the most popular web programming language, with strong implementations of both SOAP and XML-RPC, the leading ways to distribute applications using web services. But books on web services focus on writing these applications in Java or Visual Basic, leaving Perl programmers with few resources to get them started. "Programming Web Services with Perl" changes that, bringing Perl users all the information they need to create web services using their favorite language.

"There is No Free Lunch"
Time Limit: 1 Second Memory Limit: 32768 KB
One day, CYJJ found an interesting piece of commercial from newspaper: the Cyber-restaurant was offering a kind of "Lunch Special" which was said that one could "buy one get two for free". That is, if you buy one of the dishes on their menu, denoted by di with price pi , you may get the two neighboring dishes di-1 and di+1 for free! If you pick up d1, then you may get d2 and the last one dn for free, and if you choose the last one dn, you may get dn-1 and d1 for free.
However, after investigation CYJJ realized that there was no free lunch at all. The price pi of the i-th dish was actually calculated by adding up twice the cost ci of the dish and half of the costs of the two "free" dishes. Now given all the prices on the menu, you are asked to help CYJJ find the cost of each of the dishes.
