编写并调试一个模拟的进程调度程序，采用“轮转法”调度算法对五个进程进行调度。

　　轮转法可以是简单轮转法、可变时间片轮转法，或多队列轮转法。

　　简单轮转法的基本思想是：所有就绪进程按 FCFS排成一个队列，总是把处理机分配给队首的进程，各进程占用CPU的时间片相同。如果运行进程用完它的时间片后还为完成，就把它送回到就绪队列的末尾，把处理机重新分配给队首的进程，直至所有的进程运行完毕。-Write and debug a simulation of the process scheduler, using the "Web" scheduling algorithm on the five scheduling process.



Web method is a simple web method, variable time slice, or multiple queues rotation method.



A simple round-robin method the basic idea is: all ready process by FCFS queue into a queue, is allocated to the processor the first team in the process, the process takes up CPU time slice of the same.If you are running the process spent its time slice for the completion, they send it back in place at the end of the queue, the processor re-allocated to the first team in the process, process until all is finished.
