Description
bfs or dfs, or something else that is simpler (e.g. kitten and flying safely) can work for most of these. Several problems can be solved using flood fill with dfs.
For 10 Kinds of People, dfs can be used as part of an algorithm. See this problem in vol. 1 of the textbook and also see the hint. Similarly see textbook for coast.

Scoring
Pass/Fail — Ranked
Explanation:
Each problem is pass/fail. Participants are ranked by the number of solved problems, breaking ties by penalty (sum of time + 20 minutes per wrong submission, for all solved problems). Time is rounded to minutes.
