BITS PILANI, DUBAI CAMPUSINSTRUCTION DIVISIONSecond Semester 2012 – 2013Course Handout (Part – II)Date: 03.02.2013In addition to Part I (General Handout for all courses appended to the Time Table) this portion furtherspecific details regarding the course.Course No. : CS F211 ( 3 1 4 )Course Title: Data Structures and AlgorithmsInstructor-in-charge : Ms. J. Alamelu MangaiInstructors: Ms. J. Alamelu MangaiScope and Objective of the Course:This course offers an introduction to typical data structures used for representing collections of data andthe associated relations. The course is design oriented but realization and performance issues will also becovered. It covers most common deterministic data structures for linear and non-linear data as well as afew randomized data structures. The primary goals of the course are: 1) to introduce common datastructures for storing collections of data and the associated relations along with algorithms forretrieving/modifying the data. 2) to introduce techniques for designing and implementing such datastructures on modern computers and 3) to introduce formal and experimental techniques for analyzing theperformance (time and space) of such data structures.Course Pre/Co- requisite (if any) & Catalogue / Bulletin Description : Given in the Catalogue 2012 – 2013 CDText book(s) [TB]:T1.

Detailswill be intimated through a separate notification or announced in the class and the deadlines would beindicated therein. However all reports would be completed by 2 nd week of May, 2013. It is necessary thatall students stick to time schedule and do not postpone submission of reports. This will prevent extra loadduring last two weeks of class work. No make-ups would be allowed for submission of practical reports.Mid-sem Grading:Mid-sem grading will be displayed after two evaluation components or earlier when- ever about 40 % ofevaluation components are completed.Note: A student will be likely to get “NC”, if he / sheDoesn’t appear / appear for the sake of appearing for the evaluation components / scoring zero inpre-compre total.Scoring zero in the lab component / Abstaining from lab classes throughout.Makeup and Attendance policies:Make-ups are not given as a routine. It is solely dependent upon the genuineness of the circumstancesunder which a student fails to appear in a scheduled evaluation component. In such circumstances, priorpermission should be obtained from the Instructor-in-Charge (I/C).The decision of the I/C in the abovematter will be final.Attendance: Every student is expected to be responsible for regularity of his/her attendance in classrooms and laboratories, to appear in scheduled tests and examinations and fulfill all other tasks assignedto him/her in every course. A student should have a minimum of 50% of attendance in a course to beeligible to appear for the Comprehensive Examination in that course. For the students under the purview ofAcademic Counseling Board (ACB), the Board shall prescribe the minimum attendance requirement on acase-to-case basis. Attendance in the course will be a deciding factor in judging the seriousness of astudent which may be directly / indirectly related to grading.General timings for consultation:Each instructor will specify his / her chamber consultation hours during which the student can contact him /her in his / her chamber for consultation. (For details see part II)General instructions:Students should come prepared for classes and carry the text book(s) or material(s) as prescribed by theCourse Faculty to the class.Notices:All notices concerning the course will be displayed on the respective Notice Boards.Ms. J.
