there is maximum testing that and if the
one solution is 1. if one can is tested and it is the bad one then only one test needed. however, as to a process, it can be done in a of 4 tests by mixing samples from half of the cans and then mixture. if positive, the other half of the cans are dismissed negative that set of cans is dismissed. repeat three times for remaining cans. winners: [email protected] [email protected] themistocles chronis second chance winner: jay grubber, fl
