Three tasks with ids T1, T2, T3 with estimated time 10,5, 7 ms and priority 1,2,3 respectively enters to ready queue together. A new process with estimated time 2 ms and priority 0, enters the queue after 2 ms. Schedule the tasks using preemptive SJF (Shortest Job First) and priority based scheduling algorithm. Calculate execution time, waiting time, turnaround time, mention which is the best scheduling algorithm for a given problem. (0 is the highest priority)
