1. Course Description The purpose of this course is to provide the students with solid foundations in the basic concepts of data structures and algorithms. The main objective of the course is to teach the students how to select and design data structures and algorithms that are appropriate for problems that they might occur. This course is also about showing the correctness of algorithms and studying their computational complexities. This course offers the students a mixture of theoretical knowledge and practical experience. Programming language C will be used for practical work. 2. General Objectives The general objectives of this course are as follows:  To introduce data abstraction and data representation in memory  To describe, design and use elementary data structures such as stack, queue, linked list, tree and graph  To decompose complex programming problems into manageable sub-problems  To introduce algorithms and their complexity 3.
