Apply multilevel queue scheduling (MQS) consisting of two queues (Queue 1 has absolute higher priority over queue 2) Processes DO NOT change queues, NOTE: this is not MLFQ Process CPU burst time Arrival time P1 P2 P3 P4 P5 Priority queue 12 0 4 4 19 Both queues use Round Robin scheduling, with Tql-2 (Priority queue 1) and Tq2-4(Priority queue 2) Show the Gantt chart and calculate individual and average waiting time, individual and average response time and individual and average turnaround time
