The goal of this course is to deepen students' understanding of data structures and algorithms and how these can be employed effectively in the design of software systems. We anticipate that it will generally be taken in the second year of a program (and it was originally assigned a level-2 course code), but since its only pre-requisite is ITP, is it possible to take it in first year. It is an important course in covering a range of core data structures and algorithms that will be used in context in later courses.
