设有两个周期性的实时任务A和B，任务A要求每20ms执行一次，执行时间为10ms 任务B要求每50ms执行一次，执行时间为25ms 试编一调度程序按最小松弛度优先算法对这两个任务进行调度并输出每次调度时被调入运行任务的状态: (任务名，所处周期数，调度时刻，运行持续时间)。-There are two real-time periodic tasks A and B, task A once every 20ms, execution time of 10ms　mission B once every 50ms, execution time of 25ms　trial one scheduler priority according to the smallest relaxation algorithm these two tasks scheduling and output scheduling for each mission when he was transferred to run the state: (mission name, where the number of periods, scheduling time, run duration).
