I'm thinking of taking Continuous Time Finance with Iyer next semester. Do you know if it's a good class?

I can ask my friend Edward who took it last semester. It looks like he rated it a ~-399~.

An interesting rating scale. Does he have any recommendations for what classes I should take then?

Input

The input will consist of a single word, either "Best" or "Worst".

Output

Output any substring of the name of a class in the Spring 2024 Semester. You will get the lowest 'score' of all matching classes (so be specific to get more points).
