HW 5 Solutions have been posted in section C.
(04/04) Clarification HW5 For some questions you are given a running time with multiple choices in O(.) notation. Say O(n), O(nlgn), and O(n**2). If all three choices are applicable as an answer you choose the best of the three and in that case it would O(n).
(04/04) Withdrawal deadline Note that today might be the date for the withdrawal deadline. Check the Registrar's web-page.
(03/29) HW5 Available in canvas.
(03/23) Solution key for Exam 1 Available in canvas.
(03/18) Masks in classrooms (covid-19 related) I repeat a relevant sentence from the March 10, 2022 3:37pm email of the NJIT Pandemic recovery committee: "As of Monday, March 14, 2022, masks only will be required in indoor instructional spaces."
(03/14) Office hour note No office hours in breaks, exam periods, or days NJIT follows another day's schedule (and there are no office hours that alternate day).
(03/11) Exam 1 grading The exam 1 grading is almost complete. Therefore the exam will be returned the first class after the break. By that time statistics would become available in section C.4 of the course web-page. Furthermore midterm course performance guidance would become available in section C.1.a of the course web page. It will be based on HW1-HW4 and Ex1, a total of attainable 480pts. A solution key would be posted afterwards. Do not expect any information through canvas though.
(03/03) HW 4 grading The grades have been posted in canvas. HW4 is available for viewing. Read the two notes in the updated HW4 solution key.
(03/03) Email of Feb 24 Posted in canvas announcements. It contains material coverage of the exam (Exam 1).
(03/03) HW4 solution key Posted in section C.
(02/24 Update) (02/23) Exam 1 instructions The instructions (as of now) that you will see on the cover page of the exampaper are available in a link in section C.0 of the course web-page. Moreover an email would be sent out around noon time today re Exam 1.
(02/24) HW3 grading HW3 has been graded. It is available for a 14-day period in canvas starting noon time today. A solution key is available in Section C of the course web-page.
(02/23) HW4 typos or irregularities Question 4 has an array with Pascal type bounds. Do not get surprised. Moreover the smaller than 6 should be interpreted as an integer smaller than 6.
(02/17) Textbook alert We discussed in class one deviation from the textbook. a binary heap in the class and note discussion is an array, disregard the discussion of the textbook as you were told in class. Furthermore, on pages 94-98, the textbook describes some sorting implementation that it labels "Insertion-Sort" and "SelectionSort" by utilizing a PriorityQueue. You may refer to them and ignore them PQISort and PQSSort, but they have nothing to do with InsertionSort and SelectionSort as they were described in class and as every other book describes. Moreover one can draw wrong conclusion: read the last sentence of page 98 ("For example ... time.").
(02/15) HW3 HW3 is available in canvas. For problem 2a. (you may assume) n is a power of four and this is given. For problem 2c. (you may assume) n is a power of two and this was implied For problem 1b. A right parenthesis is missing g(sqrt(n)) instead of g(sqrt(n).
(02/10) HW 2 grading The homework has been graded and will become available for inspection today. A solution key has become available in section C.
(02/07), (02/02) HW 2 typo and Subject 1 typos For problem 1, you may assume that q is greater than zero i.e. 1,2,3, etc. For problem 3 the amount of space asked in the question is the space used in the multiplication other than the space occupied by the input numbers a,b,c, and d. Go to Section C.2 and question 2 is restated there. Moreover I have updated the text of question 2 of HW2. But if you have already opened HW2 in canvas to start working on the homework, you might not be able to see the corrected text until you submit that previous version of the homework. (Let me know if it is a problem and you need more than 3 submissions total.) For Subject 1 i corrected some typos related to the Binary Search slides.
(02/01) HW 2 available on canvas Practice makes perfect.
(02/01) Lectures are face to face effective NOW An email was sent out by me at 2:50pm on Fri 28 Jan towards this. Read it. It also records the classroom listed by the registrar as of that day. I will recheck the registrar information before heading to the classroom, and i suggest that you do so as well.
(02/01) Canvas Messaging and Canvas Grades Note that Canvas messaging is NOT OFFICIAL NJIT mode of communication. It is limited and is not read regularly (around once a week). Do not use it unless you are comfortable receiving an answer after seven days. Canvas grades reported are for the last attempt only. If there was manual intervention and your grade is to be (or was) adjusted this will be reflected on a grade file maintained on AFS and outside of canvas. This is for a reason: canvas has sync issues. Several of you by now have already experienced this.
(01/31) HW1 graded It is available in canvas for viewing for two week after 11am today. A solution key has been posted in section C of the course web-page.
(01/26) Webex The webex recording of all classes so far have become available in Canvas Modules (under module Subject 1).
(01/31), (01/26), (01/25),(01/19) VOP All those who submitted the verification of presence quiz have been verified as of 09:56@1/31 ~~11:27@1/26 13:32@1/25 Wed 1/19 (10:05am)~~.
(01/26) Webex The webex recording of all classes so far have become available in Canvas Modules (under module Subject 1).
(01/20) PrP pdf document Up to about 9:40am on 1/20 the PrP document in Canvas might have had a name p1610s22-1.pdf. This had to do with some undetermined canvas synchronization issue. Two files coexisted on the same space, for some reason, and the wrong one displayed. I think i have fixed the problem (deleting the two files and re-uploading the correct version) but for the sake of caution the pdf is ALSO AVAILABLE in Section C.0 of the course web-page. In section C.0 you are also going to find the md5sum of the file stored there and of the corrected file in canvas/Assignments.
(01/26), (01/25),(01/19) VOP All those who submitted the verification of presence quiz have been verified as of 11:27@1/26 ~~13:32@1/25 Wed 1/19 (10:05am)~~.
(01/19) Typo and clarification HW1 It talks about "A(n), B(n) below". There is no B(n) disregard it. There is only $A(n)$ to bring up the discussion of Document 5. Moreover, in the last question (q7) you are expected to use only multiplications i.e. no divisions.
(01/18) Before First Sync Online Class (Webex) Canvas Modules module BeforeFirstClass asks you to do certain things before the first class meeting. Moreover through Jan 30, all class meetings, but also office hour meetings will be held through Cisco Webex. Information about Webex meeting numbers has been made available in Canvas Announcements (one message for the Class meetings, one message for Office Hour meetings).
(01/11) First Posting on Course Web-Page Canvas is active. A number of messages have been posted in Canvas/Announcements. Some of them contain attachments in the form of Document 0 (Instruction), Document 1 (Syllabus), Document 2, Document 3 and Document 4. Canvas Module BeforeFirstClass instructs you on what to do before first class. (There is a module AfterFirstClass.) Beyond first class read Document 0. Verification of Presence (VoP) is setup as a canvas quiz; read Document 0 and VoP instructions when it becomes available. The class lectures are split into modules known as Subjects. Every Subject has its Canvas/Module. Navigate around the three sections of this course web-page. This announcements is in Section A (Announcements) different from Canvas Announcements. Pay attention to Section B. If you need credentials to access Section C read page 0 of Document 0. For the period Jan 18-Jan 30 Canvas contains Webex info for the class and the Office hours. They have different Meeting Numbers and (potentially) passwords. THe first two classes will be given through Webex. If you have connectivity issues, Kaltura voiceovers have been made available in advance for the topics that will be covered. I expect to record the Webex sessions and release through the module of Subject 1 in canvas.
