For this lab you must write code (python files), and, if applicable, the result(s) of running the program on (a few) test cases. This will be graded only in person in the lab. 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 a comments section (using the hash tag) in your PYTHON code.
Plagiarism (the unattributed copying of work from other sources (internet, chatGPT, fellow students,....)) will not be tolerated. You risk getting zero for your lab if it is found to be plagiarized.
Check the file "criteria.pdf" to see what to look for, and what you should take care of, in your PYTHON code.

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 Remaining Time First
Round Robin (with CPU slices of 4 seconds)

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