Liam has written a pseudocode algorithm to track gym activities and calculate points. If a member does swimming, they get 5 points. If they do cycling, they get 12 points.

The algorithm should output the total points, the number of swimming sessions, and the number of cycling sessions.

However, there is an error in the algorithm.
