Write and debug a single-channel processing system operating to wait for simulation program.
Operation waiting algorithm: respectively, a first-come first-served (FCFS), shortest job first (SJF), respond to than high preferred (HRN) scheduling algorithm.
Scheduling algorithms are required for each print job starts running each time, the completion of time, turnaround time, with the right turnaround time, and this group of operations, the average turnaround time and the weighted average turnaround time to compare the advantages and disadvantages of various algorithms
