进程调度问题

模拟先来先服务调度算法或者短作业调度算法，要求可以自动产生或者手动输入若干进程的名字、到达时间、运行时间； 响应键盘模拟时间片流逝，输出中间每个进程的运行状态，最后产生完成时间、周转时间、带权周转时间的汇总清单。

-Process scheduling simulation of FCFS scheduling algorithm, or short-scheduling algorithm, requests can be automatically generated or manually enter the number of process name, arrival time, running time　response to the passage of the keyboard simulation time slice, the output of each process running the middle, culminated in the completion time, cycle time, turnaround time with the right to a summary of the list.
