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.

Boost provides Free peer-reviewed portable C++ source libraries.
We emphasize libraries that work well with the C++ Standard Library. Boost libraries are intended to be widely useful, and usable across a broad spectrum of applications. The Boost license encourages both commercial and non-commercial use.
We aim to establish "existing practice" and provide reference implementations so that Boost libraries are suitable for eventual standardization. Ten Boost libraries are already included in the C++ Standards Committee s Library Technical Report (TR1) as a step toward becoming part of a future C++ Standard. More Boost libraries are proposed for the upcoming TR2.
Boost works on almost any modern operating system, including UNIX and Windows variants. Follow the Getting Started Guide to download and install Boost. Popular Linux and Unix distributions such as Fedora, Debian, and NetBSD include pre-built Boost packages. Boost may also already be available on your organization s internal web server.
MySQL claims to be the world s most popular open source database, and with good
reason. It is Free, runs on a wide variety of platforms, is relatively simple, easy to
configure and performs well even under significant load. By comparison to some other
popular database management systems, configuring it is quite simple, but there are still a
sufficiently wide variety of security-relevant configuration issues to make securing it a
challenge.
Cfingerd is a Free and secure finger daemon replacement for standard finger daemons such as GNU fingerd or MIT fingerd. It can enable/disable finger service to individual users, rather than to all users on a given host.
