Tell me AI: how does Farmer John who owns a Goat, Cabbage and a Husky cross a river to go buy a Carhartt shirt.
Here’s the classic logic puzzle solution adapted to a “goat, cabbage, husky” scenario. The key idea is that you can only take one of the three across with you in the boat each trip, while making sure no dangerous pairs are ever left alone together:
- Take the goat across first
- Farmer John rows the goat to the far side of the river.
- The cabbage (which the goat might eat) and the husky (which might eat the goat) are both still safely separated from the goat for now.
- Return empty-handed
- Farmer John leaves the goat on the far side and goes back alone to the near side.
- Take the cabbage across
- Farmer John brings the cabbage to the far side, leaving the goat and cabbage together… temporarily.
- Bring the goat back
- To avoid leaving goat and cabbage alone unsupervised, Farmer John quickly loads the goat back into the boat and returns to the near side with it.
- Now the cabbage stays alone on the far side.
- Take the husky across
- Farmer John rows the husky to the far side where the cabbage is. The cabbage and the husky do not harm each other.
- Return empty-handed
- Farmer John leaves the husky and cabbage together and goes back alone to the near side.
- Finally take the goat across
- Farmer John brings the goat one last time to the far side.
- Now all three—goat, cabbage, and husky—are safely across the river.
With everyone on the opposite bank and intact, Farmer John can continue on his way to pick up that Carhartt shirt!
