Input Numerical-1

The document outlines the execution of three processes (P1, P2, P3) using Shortest Job First (SJF) and Priority Scheduling algorithms. For SJF, the average waiting time is 1.67 and the average turnaround time is 5.67, while for Priority Scheduling, the average waiting time is 3.33 and the average turnaround time is 7.33. The processes are analyzed based on their arrival times, burst times, and priorities.
