Three cups problem

Hey kiddo, let me tell you about the three cups problem.

Imagine you have three cups in front of you. One cup is filled with red juice, another cup is filled with blue juice, and the last cup is empty. Your job is to move the juices around using only the cups so that the cup that was originally filled with red juice is now filled with blue juice, the cup that was originally filled with blue juice is now empty, and the cup that was originally empty is now filled with red juice.

Seems easy, right? But here's the catch - you can only move one juice at a time and you can't pour any juice out. So, how are you going to do it?

Well, the trick is to use the cups to pour the juice back and forth until the cups have the juices in the right places. You can start by pouring the red juice from the first cup into the third cup, making the third cup now filled with red juice. Then, pour the blue juice from the second cup into the first cup, making the first cup now filled with blue juice. Lastly, pour the red juice from the third cup into the second cup, making the second cup now filled with red juice. And voila! You have successfully solved the three cups problem.

See? It's like playing a game of puzzle where you need to use your thinking skills and strategy to figure out the right moves.
