Wichtel 2014 (2): Weihnachten der Schlangen
(Published on 29. January 2015, 10:24 by wichtel)
All the snakes in Puzzletown have asked for their favoured meals to Christmas and Father Christmas fulfilled these wishes to all of them. He brought for every snake at least one piece of their favourite meal and spread them all around the house. Of course the snakes were eager to swallow them. Find the positions of the snakes.
Draw some snakes into the diagram covering all cells. Each snake only likes one of the goodies, e.g. only strawberries or only raspberries but never different kinds of goodies in one snake. There may be two or more snakes of a kind, e.g. two or more strawberry snakes. A special case is the gingerbread snake. There is only one in the house and it is rather wide than long. Different from the other snakes this one is two cells wide (You can push a 2x2 square through it.) and is the shortest of all (taking the length as the number of different 2x2 squares in it). Snakes may not touch themselves, not even diagonally.
After the snakes had all taken their Christmas meal they gathered for a rest in the courtyard around the Christmas tree. Find the snakes of the upper diagram in the following grid:
The lengths of the snakes stay the same and the dimension of the gingerbread snake as well. No snake touches itself or another one, not even diagonally. The numbers at the left give the number of adjacent snake cells in each row in the right order. In the area of the Christmas tree there are no snakes.
Solution code: The lengths of the snakes in ascending order, then the number of snake cells for each column (from left to right) in the bottom diagram

Witzig, besonders weil die üblichen "Schlangentechniken" nicht (viel) nutzen.

an Krokofant: Ja, das ist richtig.
Und zu deiner zweiten Frage: Ich glaub, selbst wenn ich dazu sicher wäre, würd ich's nicht so einfach verraten ;-).

Das 2x2-Quadrat in der Lebkuchenschlange bewegt sich in Schritten von einem Feld. Zwei aufeinanderfolgende 2x2-Quadrate überlappen sich also immer in 2 Feldern. Und mit dieser Bewegung berührt sich die daraus entstehende Schlange nicht selbst.

Hmmmm...
Muss sich denn die 2x2 Schlange nicht zwangsläufig selbst berühren? Oder bedeutet diese Regeleinschränkung, dass die 2x2 Schlange aus verschiedenen 2x2 Blöcken besteht und sich nicht über halbe Blöcke (also nur ein Feld) bewegen kann?

Anleitung auf den aktuellen Stand vom 24.12. gebracht. Auch im oberen Diagramm dürfen sich Schlangen nicht selbst berühren.
