Quest about witches and inquisitors who need to get across the river
Recreation / / December 29, 2020
There are five options for the first trip: one inquisitor, two inquisitors, one witch, two witches, an inquisitor, and a witch. Let's consider them in more detail.
One or two inquisitors - options are not suitable, because there will be more witches on the shore than inquisitors, and the latter will be under the influence of the spell.
One or two witches - this is also not good, because witches do not know how to control a boat, and she herself will not float.
The inquisitor and the witch are the only suitable options.
Let's start crossing!
1. The inquisitor and the witch float from the left side of the river to the right.
2. Now you have to go back. The witch remains on the right bank, because she does not know how to control the boat, the inquisitor floats to the left bank.
3. It is impossible to send two inquisitors to the right bank, otherwise there will be more witches on the left, and this is fraught with witchcraft. This means that the inquisitor and the witch are again sent to the right bank. The inquisitor takes and drops off the lady, but he himself remains in
boatto avoid being enchanted.4. The Inquisitor returns alone to the left bank. After these crossings, things are as follows: on the left side there are one witch and three inquisitors, on the right - two witches.
5. Now you need to decide who to send to the right bank: an inquisitor and a witch or two inquisitors. If the inquisitor and the witch float, the number of the latter on the right side of the river will always prevail. It will no longer be possible to safely transport the remaining inquisitors. So, we need to focus on a pair of "two inquisitors". Then on the right bank there will be an equal number of both.
6. The boat must be returned. You cannot send one inquisitor to the left side, otherwise the witches will remain in the majority. This means that the inquisitor is going on the way back and witch.
7. Now, for security reasons, two inquisitors are sent to the right side.
8. Now only one inquisitor will sail to the left bank. Without leaving the boat, he takes one witch with him.
9. One inquisitor goes after the remaining sorceress and crosses the river with her.
10. The whole company finally finds itself on the right bank. Hurrah!
