Joseph Problem (detailed solution) and Joseph Problem SolutionPreface
I learned the queue these days, so I tried Joseph Problem, And then I failed to get through it. Finally, after dialing, I passed. I am deeply impressed with the use of queues. We recommend that you try to solve this problem if the queue trainer is working.
Body
Joseph Problem (35 points): Suppose there are N people in a circle, then the first person kills the second person, the
balancing.
To make the test simple, there are two temporary Console applications in the solution to replace ConfigCenter and LogCenter.
4) WcfExtension. Clients. Console is the Console client for testing. It should only rely on the WcfExtension framework and service contract, that is, WcfExtension. Services. Interface.
5) WcfExtension. Hosts. Console is the test Console server. It depends on service interfaces and Service implementations, as well as

VirtualizationVMware's CPU virtualization achieves CPU sharing through time slices. Sharing memory via virtualization technology is not that easy. Assume that an application requires 2 GB physical memory. Even if 2 GB virtual memory is allocated to it, the corresponding physical memory will also exist. Otherwise, the performance of the application will become poor (using disk swap memory pages ). VMware uses transparent page sharing technology to achieve a certain degree of Memory Sharing. The
