The Tower and Glass Marbles Problem.
2010
SummaryThe Catseye Marble company tests the strength of its marbles by dropping them from various levels of their office tower, to find the highest floor from which a marble will not break. We find the smallest number of drops required and from which floor each drop should be made. We also find out how these answers change if a restriction is placed on the number of marbles allocated for testing. Investigating this puzzle motivates algorithmic thinking, and leads to an interesting recursive solution.
