Algorithms and Data Structures PPT PDF SLIDES
Description. This course surveys the most important algorithms and data structures in use on computers today. Particular emphasis is given to algorithms for sorting, searching, and string processing. Fundamental algorithms in a number of other areas are covered as well, including geometric and graph algorithms. The course will concentrate on developing implementations, understanding their performance characteristics, and estimating their potential effectiveness in applications.
Course website. The course websitehttp://www.princeton.edu/~cos226includes links to course content, including programming assignments, exercises, lecture slides, and old exams. You will also use it to submit programming assignments. Readings. The following textbook is required. It contains a wealth of information beyond what we can cover in lecture; it is certain to enhance your understanding of algorithms and data structures.
