Unformatted text preview: Lecture 1 01/07/08 Basic Idea of the Course Program = Data Structure + Algorithms Course Content- Analysis tool (big-O)- Stack and Queues- Vectors, List and Sequences- Trees- Priority Queues- Dictionaries- Search Trees- Sorting (Sets)- Selection- Text Processing- Graphs Analysis Tools Data Structure- a data structure is a way of representing and storing data in a computer. Algorithms- transformation of the data structure or transformation of input data into output data. Note: - Our goal when programming is to create the best possible data structure and algorithm to represent the problem. Lecture 2 01/09/08 Math Review a b+c = a b a c a b.c = (a b ) c a b /a c = a b-c log a b = c => a c =b log b (xy) = log b x + log b y log b (x/y) = log b x - log b y log b (xy) = ylog b x Floor[x] = largest integer that belongs to x. Ceiling x = smallest integer >= x.
