Test instructionsThere are a total of n villages in a certain area, the coordinates of each village are represented by a pair of integers (x, y), and now a communication network is established between villages.There are two types of communication tools, namely the common line and the wireless communication satellite equipment that need to be laid.Only the K villages are equipped with satellite equipment, an
head, in fact, we have little relationship. The ground terminal, in fact, is our popular GPS, it can receive your head of those flying satellite signals, and then based on the signal to calculate your current position. Common terminal has car navigation GPS, mobile phone built-in GPS and hiking outdoor GPs and so on. The accuracy of the general civil class is about 10 meters. When using GPS, it is necessary to be able to receive GPS
Q Box is your private pet, the same as the rest of the desktop pets, he is not a only can run on the table jumping on the vase. He will remember every word the master taught him. If you don't teach a question, he will surf the internet for answers from the rest of the host to teach his pet. Q Pet will first think of using you to teach him to answer. If you don't teach a question, he will surf the internet to answer the rest of the owner's pet. However, this pet will be more and more like you. Q
Our "Chang ' E Satellite" has been flying around the moon, really exciting moment! Let's use PowerPoint to complete an example of "Chang ' E around the moon".
First, prepare the material: Star, Moon and "Chang ' e satellite" pictures. (Moon Chart and satellite chart best use picture processing software to dig off the background.) )
sharp weapon to solve the problem of communication network access 。

competitors, S50D has no advantage in weight and thickness, just slightly better than the satellite C50.
S50D's keyboard is also used for smooth plastic material, but it is more reasonable in terms of layout. S50D number key is large enough, and there is a large space bar and SHIFT key, overall, in the use of the process is more convenient.
Although the weight of the s50d is somewhat large, we don't think it is necessarily a bad thing.

Visual Studio. NET makes it very easy to use resource files, so why not take advantage of them? You can store just about anything in them, including strings, images and persisted objects, but the most useful for web apps is strings. I was originally using them for error message management, but realized that they cocould more, especially in a text-intensive application where having packaged units might be beneficial. another advantage is their read-only nature; people (
application-based business policy. If a Wan line is unavailable or cannot meet the required performance requirements, the policy-based multi-path technology automatically and transparently transfers the application transmission stream to other available WAN links, ensure that the application transmission stream continues to be transmitted effectively and reliably.
Reduces the risk of line migration
Policy-based multi-path technology allows users to use low-cost Wan transmission technology (such
