How do you calculate waiting time Round Robin algorithm?

To calculate the waiting time in the Round Robin scheduling algorithm, follow these steps: First, determine the completion time for each process by simulating the execution of processes in a cyclic manner for a fixed time quantum. Next, calculate the turnaround time for each process by subtracting the arrival time from the completion time. Finally, the waiting time for each process is found by subtracting the burst time from the turnaround time. The formula is: Waiting Time = Turnaround Time - Burst Time.
