First, demand analysisAt present, with the building of the use of the elevator more and more frequently, elevator safety is also more popular attention to the public,A convenient and safe elevator is not only the façade of a building, but also the pursuit of more people.Second, I request1.1~18 Floor Elevators must have up to two buttons on each floor (except 1 and 18 layers)2. Each button is called by the nearest principle to call any of the two elevators.3.1~7 floor elevator can not stop, and p

Since the deleted points are not re-added, each point is deleted at most, with a complexity of NLOGN.Combined with the complexity of the above series of operations Nlogn, the total complexity remains nlogn.Code1%:p ragma GCC optimize (2)2#include 3 #defineLL Long Long4 using namespacestd;5 Const intn=100005;6Vector int>Son[n];7 intN,m,ro[n]; LL S[n],c[n],f[n],ans;8 structLFT {intL,r,d,w;voidCL () {

obtain all available supervisor first, infer that the supervisor available standard is whether there is a spare slot, that is, whether all supervisor.slots.ports specified port is occupied, and then calculate the need to allocate a few woker. Since a woker corresponds to a port, and of course the collection of this information is from zookeeper, we now analyze the core code of the allocation:Workermaker.javaNote that result is the slot required for this job.

1. Project requirements of the banking dispatch system Simulation to achieve the logic of banking scheduling system, the specific requirements are as follows: Ø There are 6 business windows in the Bank, window 1-4 is a normal window, window 5th is a quick window, and 6th window is the VIP window. Ø There are three types of customers: VIP customers, ordinary customers, fast customers (handling such as electricity and water charges, such as customer ser

Calculation timePriority computing is no longer focused on the scheduler's choice of candidate processes, and as long as the status of the process changes, it is possible for the core to compute and set the dynamic priority of the process:A) Create a processIn Wake_up_forked_process (), the child processes inherit the dynamic precedence of the parent process and are added to the ready queue in which the parent process resides.If the parent process is not in any ready queue (for example, it is a

. Imagelocalitypriority: Rate based on whether the pod is operating on the host. Imagelocalitypriority will determine whether the required mirror of the pod is already on the host, and return a 0-10 rating based on the size of the existing mirror. Returns 0 if a desired mirror is not present on the host, and if a partial mirror image is present on the host, the value is determined based on the size of the mirrors, and the higher the image, the more the score is.

However, if the server has just received the message, has not yet been able to write to the hard disk, it hangs up, this still cannot avoid the loss of the message. Second, fair dispatch The previous example can be implemented to send a

We continue with the inside winx's message dispatch. Now we have entered the most critical part-How winx distributes messages. In principle, winx's message dispatching function (dispatchmessage) is actually not much different from the previous article: winx's message dispatching mechanism (continued), but it is more intelligent. Among them, the most important thing is that winx introduces a technique that can be used inCompilation phaseDetermines whet

contract is established. Assertions are obviously the best choice, but not all programming languages have assertions. Therefore, forced language imitation will inevitably lead to code redundancy and readability improvement. For example, before net4.0, there was no assert concept. After net4.0, the concept of contractual programming was fully introduced, greatly improving the availability of contractual programming. In addition, contractual programming is not standardized, so the definitions and
