Problem 1
Lecture 8
While browsing the library, Hermione stumbles upon an old book containing game logs
for all Quidditch matches played at Hogwarts in the 18th century. Quidditch is a sport
played between two houses. It features three types of balls:
Quaffle: Worth 10 points when used to score a goal.
Bludger: Does not contribute points. Instead, used to distract the other team.
Snitch: Worth 150 points when caught. This immediately ends the game.
A game log is a list of actions that occurred during a Quidditch match. Each element of
a game log is a two-letter string where the first letter represents the house that
performed the action ("G" for Gryffindor, , "H" for Hufflepuff, "R" for Ravenclaw, "S"
for Slytherin) and the second letter indicates the type of Quidditch ball used in the
action ("Q" for Quaffle, "B" for Bludger, "S" for Snitch). For example, "RQ" in a game
log represents Ravenclaw scoring with the Quaffle to earn 10 points.
Hermione writes a function, logwarts , to calculate the final score of a Quidditch match
based on the actions in the game log. The inputs are a game log (a list, as described
above) and the full names of the two houses competing. The output is a list of length 4
containing the names of the teams and their corresponding scores. Example behavior
is given below.
