Question

Specify a map class, named StringIntMap, which maps strings to integers. Maps allow an
existing mapping to be looked up. Maps are also mutable: new pairs can be added to a map, and
an existing mapping can be removed. Be sure that your data type is adequate.
I have a exercises like that but i don't know what it want to tell me, i don't know what i must to do. Can somebody explain it for me? plsssss
Thank you so much

Answer 1

I think the exercise telling you to:

1. Create a custom class named StringIntMap.

2. The class serves as a collection of key-value pairs, where string is the key, and integer is the value.

3. Add a search method to seek for an item in the collection class, using a string input as the search term.

4. Add methods to add and remove item(s) from the collection.

That's how I see it, hope it helps a bit; and good luck with the exercise implementation 👍
