Write a computer program to simulate Round Robin scheduling.

• Bring in your code in class to demonstrate as it runs. You will show me what you will have. You will always get partial credit even if the program does not run properly.
You have the code for a) arrival times and service times generation and b) Gantt chart drawing of RR from previous assignments.
Now in this project you will have to combine the two codes, make few changes according to the specification mentioned below and make the program run.

Round Robin
• Consider 100 processes. Process arrives at different times with different service times. They have different arrival times.
• The generated interarrival times will fall between the minimum value of 4 and maximum value of 9. In other words, all the 99 generated numbers will be between the range of 4 and 9.
The generated services times will fall between the minimum value of 2 and maximum value of 5.
• Upon arrival, a process can be appended at the end of the ready queue, top of the queue, or right after the current process, which is in service at the time of arrival. You choose the option you would like to implement.

• Process will have:
 ID
 Service time
 Arrival Time
These are input variables for each process.
• As time goes on, processes will be picked up by the dispatcher one at a time from the ready queue and will be allowed to execute for one quantum
o Quantum will be a variable in your program. Use quantum = 1 and then 3.
o Your program should be able to use any value for context switch, CS. Use CS = 0 to start with.
o Your program should also have a variable to represent the simulated clock time.
Simulation will start with clock time =0. Assume that the first process arrives and
starts at clock time 0.

• Main program will call various subprograms/ functions/modules as needed.
• If a process completes before the time quantum has been finished, do not waste the time just doing nothing. Let another process execute for one full quantum following RR algorithm. In other words, a process will get one quantum or less of service at a time.
• Your program
a) will calculate and output the following for all processes.

-Start time
-End time
-IntitialWait time
-TotalWait time
-Turnaround time

Sample solution

Dante Alighieri played a critical role in the literature world through his poem Divine Comedy that was written in the 14th century. The poem contains Inferno, Purgatorio, and Paradiso. The Inferno is a description of the nine circles of torment that are found on the earth. It depicts the realms of the people that have gone against the spiritual values and who, instead, have chosen bestial appetite, violence, or fraud and malice. The nine circles of hell are limbo, lust, gluttony, greed and wrath. Others are heresy, violence, fraud, and treachery. The purpose of this paper is to examine the Dante’s Inferno in the perspective of its portrayal of God’s image and the justification of hell. 

In this epic poem, God is portrayed as a super being guilty of multiple weaknesses including being egotistic, unjust, and hypocritical. Dante, in this poem, depicts God as being more human than divine by challenging God’s omnipotence. Additionally, the manner in which Dante describes Hell is in full contradiction to the morals of God as written in the Bible. When god arranges Hell to flatter Himself, He commits egotism, a sin that is common among human beings (Cheney, 2016). The weakness is depicted in Limbo and on the Gate of Hell where, for instance, God sends those who do not worship Him to Hell. This implies that failure to worship Him is a sin.

God is also depicted as lacking justice in His actions thus removing the godly image. The injustice is portrayed by the manner in which the sodomites and opportunists are treated. The opportunists are subjected to banner chasing in their lives after death followed by being stung by insects and maggots. They are known to having done neither good nor bad during their lifetimes and, therefore, justice could have demanded that they be granted a neutral punishment having lived a neutral life. The sodomites are also punished unfairly by God when Brunetto Lattini is condemned to hell despite being a good leader (Babor, T. F., McGovern, T., & Robaina, K. (2017). While he commited sodomy, God chooses to ignore all the other good deeds that Brunetto did.

Finally, God is also portrayed as being hypocritical in His actions, a sin that further diminishes His godliness and makes Him more human. A case in point is when God condemns the sin of egotism and goes ahead to commit it repeatedly. Proverbs 29:23 states that “arrogance will bring your downfall, but if you are humble, you will be respected.” When Slattery condemns Dante’s human state as being weak, doubtful, and limited, he is proving God’s hypocrisy because He is also human (Verdicchio, 2015). The actions of God in Hell as portrayed by Dante are inconsistent with the Biblical literature. Both Dante and God are prone to making mistakes, something common among human beings thus making God more human.

To wrap it up, Dante portrays God is more human since He commits the same sins that humans commit: egotism, hypocrisy, and injustice. Hell is justified as being a destination for victims of the mistakes committed by God. The Hell is presented as being a totally different place as compared to what is written about it in the Bible. As a result, reading through the text gives an image of God who is prone to the very mistakes common to humans thus ripping Him off His lofty status of divine and, instead, making Him a mere human. Whether or not Dante did it intentionally is subject to debate but one thing is clear in the poem: the misconstrued notion of God is revealed to future generations.
