HW6: Regarding output

[Neha]

Hi,

In case you are trying to check out a book that is already checked out
what would be the expected output?

for example, if the instructions are
INSERT 10 "Data structures and algorithms"
CHECKOUT 10
CHECKOUT 10

what should be the output of the second checkout?

Hi,

 

We won't check this. We may try to check out a book that hasn't been inserted at all in the hash table. In this case, the output syntax should be notfound.

Hi,

 

So I know you won't check the case of trying to check out a book that is already checked, but that is one

of the possibilities for the checkOut function so we have to code for it.  We can't just leave that uncoded. 

 

So to repose the question:

 

If we are trying to check out a book that has a status of CHECKEDOUT,

should we output:

CHECKEDOUT

or

NOT FOUND

 

Thanks,

Ted

Hi,

 

If you are insistent, :) then just print out: notfound, because checkedout means that the process is successfull, but it is not in this case.

Ahmad or Mario,
Is it possible to get the output for the example in the HW? Usually
the HW description provides us with an example of an input and its
output and I do not see it for this assignment (unless I am missing
something or confused)


Can we get the output for the given input:

INSERT 57 "Twenty Thousand Leagues Under the Sea"
INSERT 1000 "Julius Caesar"
INSERT 2014 "King Lear"
INSERT 170112 "Tom Swayer"
PRINT
CHECKOUT 1000
CHECKOUT 57
PRINT
RETURN 1
DELETE 2014
PRINT
DELETE 57
PRINT



Thank you.

Hi,

 

It is mentioned clearly in the HW description. For example, for insert:

Output Syntax:

< SUCCESSFUL|COLLISION|EXISTS > bucket <int>: book id <id>

for print,

BUCKET 0: <int> "<title>" AVAILABLE, <int> "<title>" CHECKEDOUT

BUCKET 1: <int> "<title>" AVAILABLE

BUCKET 2: empty

BUCKET 3: empty

BUCKET 0: <int> "<title>" AVAILABLE, <int> "<title>" CHECKEDOUT,<int> "title" AVAILABLE.

I think it is clear.

Regards,

Ahmad

[Ted Spradley]

Thanks Ahmad.

 

Ok.  In the case of trying to check out a book that has a status of CHECKEDOUT,

we output:

NOT FOUND

 

One more question.  For all of us to have consistent output.

 

In the case of trying to return a book that has a status of AVAILABLE,

we output:

NOT FOUND

or

AVAILABLE?

 

Thanks,

Ted

[Josh]

what about the "BEGIN PRINT" and "END PRINT" lines? Should those be
output each time we print the bucket contents?

I know this is minor, but minor mistakes still get points
deducted. :)

Thanks,

Josh

Hi again,

 

Another question:

 

The order of the list in each bucket.  When doing INSERT do you have a preference if the book is inserted at the head or the tail of the list?

 

Thanks, Ted

[Ted Spradley]

Josh, I read the spec as those lines being included to be a delimiter for
the print output.

Hi,

 

Yes. The first book in the bucket should be the first which was inserted. I won't have cases to return a book that is available. Keep it available for your implementation. Let us also keep the status as checkedout if you want to checkout a book that has already been checked out. I think this is more logical. 

 

Regards,

Ahmad 

[Ji Qing]

Ahmad,

 

keep the status as checkedout if you want to checkout a book that has already been checked out,

 

keep the status as available if you want to return a book that has already been returned,

 

 and we should output "NOTFOUND" for these two cases, right?

 

Thanks!

[ahmad qawasmeh]

Hi,

 

What do you mean? You are contradicting yourself. As I said, If there is a command to checkout a book that has a checkedout status, then keep the status as it is (checkedout). If there is a command to return a book that has available status, then keep also the status as it is (available). 

 

Regards,

Ahmad

[Lucas Hawk]

He is not contradicting himself. He is asking about the output. 

If book 13 is checked out, and you send the command "checkout 13", what is the output? Is it the same as if the book was available? Regardless of the current state of the book (checkedout vs available) it should output "checkedout bookID"??

That's the question...

[ahmad qawasmeh]

Hi,

 

I told you. If the status for book id 13 is checkedout and you have the command checkout 13. Output checkedout. In the case that there is a book with id 14 with a status available, and you have this command: return 14. Output available. I hope it is clear now.

 

Regards,

Ahmad

[Ted Spradley]

Hi Ahmad,

 

I hate to bother you on this question.  Regarding output in the case of the command 'CHECKOUT 13' and bookID 13 already has a status of CHECKED out.  I think you have answered this question differently and I would like to clarify please.

 

Earlier in this thread I posted:

But, in the post immediately preceding this one you responded as highlighted.

 

To me these answers appear to conflict.  Your first answer of output 'NOTFOUND' seems logical since the operation did not result in a book being checked out successfully.  Your second answer just below could mean that you were tired. (understandable)

 

Could you point out for me if the answers do not conflict or if they do, then which output should we use please?

 

Thank you,

Ted S.

Hi Ted,

 

Yes. At first, I told you something different, but I think it is more logical to keep the book as checkedout when you have a check out command for an already checkedout book. The same applies for return an available book. I think it is better to print out available. I am sorry about this, but as I told you, I think it is more logical. I appreciate your understanding and cooperation. Let me know if you have any more observations or concerns.

 

Regards,

Ahmad  

[Joe]

So I'm kind of confused now. You are saying "to keep the book as
checkedout" does that mean that's what you want us to cout or that's
what the status is going to be?

If you are returning a book that is already available what should the
output be?
If you are checking out a book that is already checked out.. Should
the output print "checked out" or "not found" when you try to check it
again?
The status of the book is obviously going to be listed as checked out
so should that be our output

[ahmad qawasmeh]

Hi,

 

Both. The status and the printing out.

The answer for question 1: available

The answer for question 2: checkedout

I hope you are not confused now.

 

Regards,

Ahmad

[Joe]

Thank you Ahmad!
