This kata looks quite simple, but a bit tricky since there are things to consider, which are easy to miss. Anyway, interesting kata!!:D

Though this is very interesting kata, I think the instruction given is not very clear.
For example, the number of cells and the value each cell holds should be distinuguished clearly, which was not the case here.
It would be better if some kind of images like circular tape & memory cells are provided to help others to understand this kata!

Please update the random test..
