🧠The 12 Coins Puzzle (The Counterfeit Weigher)
You have 12 identical-looking gold coins. One is counterfeit and has a slightly different weight (you don't know if it's heavier or lighter!). With a balance scale, what is the minimum number of weighings needed to guarantee finding it?
💬 Could you write down the exact branching strategy for all 3 weighings? Try it in the comments! (Solution in first comment 👇)
