2. Consider a CPU that has to run a bunch of jobs. You are asked to develop a scheduler for the CPU. Your program should run in a loop, each iteration of which corresponds to a time slice for the CPU. Each job is assigned a priority, which is an integer between 20 (highest priority) and 19 (lowest priority), inclusive. From among all jobs waiting to be processed in a time slice, the CPU must work on a job with highest priority. In this simulation, each job will also come with a length value, which is an integer between 1 and 100, inclusive, indicating the number of time slices that are needed to process this job. For simplicity, you may assume jobs cannot be interruptedonce it is scheduled on the CPU, a job runs for a number of time slices equal to its length. Moreover, each time a job has spent x time slices in the waiting line its priority is increased by 1. Notice that after the priority of a job is increased its waiting time restarts from 0. Your simulator must output the name of the job running on the CPU in each time slice and must process a sequence of commands, one per time slice, each of which is of the form add job name with length n and priority p or no new job this slice. I want Python code using priority queue.
