this one is actually super easy tbh
You have 12 visually identical metal coins. One of them is counterfeit — it looks the same but its weight is different (you don’t know whether it’s heavier or lighter). You have a balance scale (compares two groups and tells you which side is heavier, or if they balance). Using the scale only three times, identify which coin is counterfeit and whether it is heavier or lighter.

Rules: you must decide which coins to put on the scale each weighing based only on previous results (i.e., adaptive strategy). Give the plan and how the outcomes uniquely identify the counterfeit coin and its weight difference.
