程序主要运用向量 将数据进行排序 构造了Thread类和Node结构，以及切换，读入函数，FCFS与RR算法运用的队列，最后计算出各项包括utilization，serviceTime，ioTime等各项数据，然后输出结果-procedures will primarily use vector data structure sort of Thread and Node category structure, and switching, read into the function, RR FCFS queue algorithm for use with the queue, Finally calculated including all utilization, serviceTime. ioTime and other data, and then output the results
