Draw out the GANTT chart for the following processes using SJF scheduling. However, in doing so, add 1 unit of delay each time a context switch occurs. So, for example, if Task A finishes at 10, Task B would not start until 11. We are assuming all tasks arrive at time zero. Once you have completed the GANTT chart, calculate the average waiting and turnaround times. Task Execution Time A 100 B 70 20 D 20 E 40
