can we choose a server product suitable for enterprise development? First, it is necessary to master some server knowledge. As we all know, in enterprise operations, servers usually perform data storage, applications, and other tasks. different services have different requirements for server configuration. For example, generally, database servers have high requirements on server hard disk capacity, WEB application servers have high requirements on processors and memory, and game servers have hi

should select a 24-port switch. ⑤ View Management Performance In the past, many low-end vswitches were non-managed. These products are easy to configure and can only use ASIC solutions. Because these vswitches are not equipped with processors, their prices are relatively low. However, these vswitches are not highly flexible and cannot meet specific requirements. In recent years, with the increasing competition in the market of low-end switches, management switches with processors have also emer

This is my first question of slope optimization, which is a souvenir. First, perform filtering, and then the dynamic planning expression will soon write out f (I) = min (f (I) + B [J + 1] * A [I]). Then we need to optimize the slope. Obviously, everything here is monotonous, so we only need to maintain the monotonous queue. The cal function calculates the slope. For details, refer to the Code (refer to others). You need to exercise more in the future. 1 #includeView code Bzoj 1957 land
