Welcome to DSCI 221: Data Structures and Algorithms for Data Science!

In this course, we’ll explore how the right data structure can turn an impossible problem into a trivial one. From the magic of hash tables (how does Shazam identify a song in milliseconds?) to graph algorithms (what’s the cheapest flight to Tokyo?), you’ll develop the algorithmic thinking that separates good programmers from great ones.

Getting started:

Read the syllabus for course policies and requirements
Check the schedule on the home page to see what’s coming up
Come to class ready to think about puzzles!

See you in class!
