For this lab you must submit all source code (python files), and, if applicable, the result(s) of running the program on (a few) test cases. This should be sent in as a file upload/attachment via CANVAS (not directly by email). The source code must be well presented (indenting, spaces, reasonable variable/function names, etc.) and must include comments (as a rough guideline - aim to have nearly as many comments as lines of code). Any questions asked should be answered by typing the answers into the relevant box on the CANVAS upload form, or by including the answer in comments in the PYTHON source code..
This material should be uploaded before the deadline of 5pm Friday February 16th., 2024. You will lose 20% for each day (or part of day) the lab is late.
Plagiarism (the unattributed copying of work from other sources (internet, fellow students,....)) will not be tolerated. You risk getting zero for your lab if it is found to be plagiarized.

A set of processes (lets say n of them, denoted by P₁, P₂,....,P_n) is sent to a CPU. The processes arrive in the order given, at times t=0, t=1,...t=n. The duration (in seconds) of these processes is given (d₁, d₂,....d_n). Write a PYTHON program which reads in these durations as input data from the user, and which calculates (a) the average waiting time and (b) the average turnaround time for the processes. These two numbers should be calculated for the scheduling policies of

Shortest Job First
Round Robin (with CPU slices of 5 seconds)

Test your program on the process durations [5,12,3,2,7,6,8,10,9] and [2,9,8,13,4,5,11,6,2,10] and report the results in both cases for the times (a) and (b) (submit these results in CANVAS when uploading your program).
