Final answer:
The means-end heuristic includes breaking down the problem into subgoals. Having prior knowledge of a problem helps to solve it when the problem is unfamiliar.
Step-by-step explanation:
The means-end heuristic includes breaking down the problem into subgoals, which is not included in the other heuristics mentioned. This heuristic involves identifying the differences between the current state and the desired state and then creating subgoals to bridge this gap. Having some prior knowledge of a problem helps to solve it when the problem is unfamiliar because prior knowledge can provide a foundation for understanding the problem and formulating potential solutions.
