说明：  操作系统中的进程调度，进程调度模拟程序：假设有10个进程需要在CPU上执行，分别用：先进先出调度算法；基于优先数的调度算法；最短执行时间调度算法 确定这10个进程在CPU上的执行过程。要求每次进程调度时在屏幕上显示：当前执行进程；就绪队列；等待队列
(operating system process scheduling, process simulation scheduling procedures : Assuming a 10 CPU in the process of implementation, respectively : FIFO-scheduling algorithm; Based on the number of priority scheduling algorithm; shortest execution time scheduling algorithm to determine which 10 of the CPU the process of the implementation process. Scheduling requires every process when displayed on the screen : the current implementation process; Ready queue; Waiting for the queue)
