Final answer:
When a string contains multiple keywords, a reply method should prioritize responses based on the context or a predefined hierarchy. Changes to the getResponse method may involve adding a priority system to manage multiple keywords efficiently, ensuring relevant and coherent replies.
Step-by-step explanation:
When more than one keyword appears in a string such as "My mother has a dog but no cat," a method that manages responses must prioritize which keyword to respond to first. Prioritizing involves deciding which keyword is more important in the context of the conversation or based on a predefined hierarchy. In the reply method, this could mean prioritizing keywords related to the user's immediate need or preference. For example, if the user's context suggests they are more interested in dogs than cats, the keyword 'dog' should be prioritized in the response.
To accommodate multiple keywords in the getResponse method, changes may include implementing a priority system where each keyword has an associated weight or rank. This system helps determine which keyword to address first in the response. The implementation of a priority or weighting system will ensure the reply method generates a contextually relevant and coherent answer when presented with multiple keywords.
