Q1: Erroneous inputHere are two one-line inputs that give error messages if you type them into the interpreter:
^
"
Where are each of these errors generated? Why are they generated in different places?Q2: Valid inputSummarize what the tokenizer does when a user types the following at the interactive prompt:"Example string"Here's the start: The interactive prompt is produced by Lox.runPrompt(), which calls Java's built in readLine() to get a line of input. When the user enters that line as input, the interpreter calls Lox.run("Example string"). Lox.run() then creates a new instance of the Scanner class, and calls scanTokens() on it.Starting from the call to scanTokens(), summarize what happens.Q3: Add a new operator(a) Add a new operator ^ for exponentiation, which tokenizes to POWER. This would let us write things like x = x^2; to square a number.Hint: This should work very similarly to +, -, /, and *, and requires changes in two files.For this question, include your actual code in the submission. That can be either a link to a repl.it, or screenshots/code in your submission document.(b) What if we wanted to use ** for exponentiation instead, like Python does? This would let us write x = x**2; instead. How would that change be different?You don’t have to actually implement this one, just answer in a sentence or two.

Alberto Iglesia is currently awaiting receipt of his permanent residency card. He was granted conditional permanent residency in 2011 for a period of two years and given a conditional permanent residency identification card. He is a legal alien. His conditional residency expired on January 12, 2013. He called USCIS two weeks prior to his conditional residency expiring, and they told him to simply keep checking the mail for his permanent residency interview date. It is now April 12, 2013. Alberto called USCIS and told them that he has not received anything in the mail. He was told to call a local field office of USCIS and schedule an appointment to have his conditional residency extended as the caseload is now backlogged and it will take longer than expected for his permanent residency interview to be scheduled. After attending his appointment, Alberto’s conditional residency was extended until December 31, 2013. However, the only proof of his extended conditional permanent residency status is a stamped extension date of December 31, 2013 on his passport. His actual conditional permanent residency identification card still reflects the expired date of January 12, 2013.On his way home from work one day, Alberto was pulled over by the police for having an expired vehicle tag. After reviewing Alberto’s identification, the police learn that his conditional permanent residency expired 3 months ago. Alberto tries to tell the police that his conditional residency was extended until December 31, 2013, but they do not believe him as he has no proof of his extension because he does not travel to work with his passport on hand. Alberto is taken into custody. Shortly thereafter, he gets a Notice to Appear stating that he will be deported for remaining in the country illegally after his conditional permanent residency has expired. Alberto hires an attorney to assist him with his claim. At the individual merits hearing, the judge did not allow Alberto to call witnesses or present evidence. The judge made his ruling to have Alberto deported after seeing that his permanent residency card was expired. The judge stated that no further proof was needed, and that the expired card “speaks for itself.”Alberto’s attorney is filing an appeal to the Board of Immigration Appeals based on the fact that Alberto was denied his due process rights by not being able to call witnesses or present evidence at the hearing. She believes that Alberto should never have been arrested, but is not as concerned about this issue as the police likely have a good probable cause argument for the arrest. The attorney asks for your help in drafting the brief. She tells you that there is a 1978 case from the United States District Court for the Western District of Pennsylvania that discusses the due process issue that she would like for you to incorporate into the argument portion of the brief. THIS MUST BE INCLUDEDYour assignment is to draft this brief for the attorney using the facts as stated and based on her due process concern outlined above. The brief should contain a short summation of the facts, an argument section regarding due process, and a conclusion. There is an exhibit that should be attached (only by reference, not physically attached) that would be very helpful in making the argument on Alberto’s behalf. You may refer to pages 289-299* in your book for guidance on the format. Will attach after bid on assignment Is complete
