Answersyou have 12 coins. one of them is counterfeit. all the good coins weigh the same, while the counterfeit one weights either more or less than a good coin. your task is to find the counterfeit coin using a balance-scale in 3 weighs. moreover, you want to say whether the coin weighs more or less

than is should and, and this is the real kicker, your weighs must be non-adaptive. that is, your choice of what to put on the balance for your second weigh cannot depend on the outcome of the first weigh and your decision about what to weigh for round 3 cannot depend on what happened on either your first or second weigh. for example, you can't say something like "take coin #1 and coin #2 and weigh them. if they balance, then take coins 3,4,5 and weight them against 6,7,8...if 1 and 2 don't balance, then weigh #1 vs #12..." you
have to say something like:
round #1: do this
round #2: do this
round #3: do this
if the results are left tilt, balanced, and left tilt, respectively, then coin #11 is heavier than it should be.| Report Duplicate | Flag | PURGE
