Programming Assignment Submission Guidelines

• Your program should be in such a form that it can be read by a lisp interpreter without errors that will halt execution of the interpreter. This can be tested by using the function:

  (load "/home/someuser/somedir/somefile.lisp")

• All functions and statements which are illegal should be commented. That way on a 10 question programming assignment, your bug at problem #3 does not force the interpreter to stop, so then the grader never sees the output from problem #10.

• Try to avoid all warnings when displaying your output, and never allow the execution to halt for any reason.

• If the function has more than one distinct part (ie. if you're asked to do something iteratively and recursively) make sure that you provide separate names for each function.

• Show all output that adequately displays the functionality you are trying to exhibit. This means that if your solution does three functions, then show output which demonstrates all three.

• Provide additional comments, where necessary, which explain the unobvious.

• All functions should print the problem, then print the output. If the problem is something simple that doesn't require you to make a function, then you may want to wrap this in another function that easily prints your output. See the example below:

  (defun cubed (x) (* x x x)) (defun test_cubed () (print '(cubed 10)) (cubed 10))

  Then the output will look like:

  (CUBED 10) 1000

• All text based answers intermersed with a programming assignment should also be included in the document source code. These should simply be commented so then the statement:

  (load "./filename")

  - does not exit because of the interpreter attempting to execute your 'plain text'.

  ; Number x ; ------------------------------------------------- ; This is dummy text ; This is dummy text ; Number y ; ------------------------------------------------- ; This is dummy text ; This is dummy text

  Example of Using the Submission Conventions

  ---

  • This example is the solution of the first programming assignment which is also available at http://www.mcs.drexel.edu/~uccera/class/CS380/pa2.soln.lsp.

  • An example of loading a file using these conventions is:

    USER(5): (load "./pa1.soln.lsp") ; Loading /home/chris/class/CS380/week3/pa1.soln.lsp T

  • Now an example of running the provided I/O function to demonstrate the output to the grader:

    USER(6): (make) (CONS 'A '(B C)) (A B C) (CONS 'A (CONS 'B '(C))) (A B C) (CONS 'A (CONS 'B (CONS 'C NIL))) (A B C) (NESTED_LISP '(A B C D E F G)) NIL (NESTED_LISP 'A) NIL (NESTED_LISP '(A B C D (E F (G H I J)))) T (UN '(A B C) '(B A D)) (A B C D) (POS_REC+ '(9 8 7 6 5 4 3 2 1)) (9 9 9 9 9 9 9 9 9) (POS_ITER+ '(9 8 7 6 5 4 3 2 1)) (9 9 9 9 9 9 9 9 9) (POS_MAPCAR+ '(7 6 5 4 3 2 1)) (7 7 7 7 7 7 7) (PRO_REC '(1 2 3 4)) T (PRO_REC '(1 2 3 5)) NIL (PRO_REC '(1 2 3 4 10)) NIL (PRO_REC '(1 3)) NIL (PRO_REC '(1 2)) T (PRO_REC '(1 2 3 4 5)) T (PRO_ITER '(1 2 3 4)) T (PRO_ITER '(1 2 3 5)) NIL (PRO_ITER '(1 2 3 4 10)) NIL (PRO_ITER '(1 3)) NIL (PRO_ITER '(1 2)) T (PRO_ITER '(1 2 3 4 5)) T (CA) 0 (CA 'A) 1 (CA 'A 'B 'C) 3 (CA 'A '(B C)) 2 (CA '(A '(B C))) 1 (CA 'A '(B '(C D))) 2 (CA '(A B C D '(E F G))) 1 (CA '(A B C '(D E '(F G)))) 1 (CA '(A B C '(D '(E F)))) 1 (C 5 0) 1 (C 5 1) 5 (C 5 2) 10 (C 5 3) 10 END_OF_TEST_OUTPUT
