Priority Clinic
The clinic robot needs a smarter line! Build a rule that helps urgent patients first while everyone else keeps their turn.
🧠 Before we start
You already know that a sequence keeps steps in order and a condition makes a choice. Today they work together in a priority queue: important jobs can move ahead, but matching jobs stay in arrival order.
