What’s new?
Here’s what’s new in CS50x 2018 vis-à-vis CS50x 2017!
Lectures
Whereas CS50x 2017’s lectures were largely shot without a live audience, CS50x 2018’s lectures were shot with a live audience, among them some of CS50x’s own students from around the world!
CS50x now introduces dynamic programming (in Week 6, continued), thanks to Benedict Brown at Yale.
CS50’s lectures are now professionally subtitled not only in English but also in Spanish!
Problem Sets
Whereas problem sets used to be graded only on the basis of correctness, they will now be graded on the basis of style as well!
Problem Set 3 used to be about the Game of Fifteen, but it’s now about music! You’ll learn to read sheet music, learn to read code, convert musical notes to frequencies, and synthesize songs.
Problem Set 5 now has a leaderboard via which you can compare your code’s utilization of time and space against classmates'!
Problem Set 6 used to introduce sentiment analysis, but it now introduces document similarity. In the less-comfortable version, you’ll implement a program that compares two files for similarities and implement a website that highlights similarities across files; in the more-comfortable version, you’ll implement a program that measures the edit distance between two strings and implement a web app that depicts the costs of transforming one string into another.
And greedy
has been renamed to cash
so that Problem Set 1 now offers a choice between cash
and credit
. Ha!
