Assuming a single-processor system with four jobs, their submission and execution times are as shown in the table below (time units: hours, calculated in decimal, and the current time is 8.0). If a preemptive priority scheduling algorithm is used (with lower priority numbers indicating higher priority), answer the following: (1) In what order should the jobs be scheduled? Provide an analytical process. (2) Calculate the average weighted turnaround time. (3) Does this scheduling algorithm lead to starvation? If yes, how can it be resolved
