In the context of this exercise, can multiple keys of a hash map have the same value?
Yes, different hash map keys can indeed map to the same value. Values are not unique. However, the keys should be unique.
For instance, we may have the following table of emails (key) and the associated names (value).
''' Key Value firstname.lastname@example.org Abraham email@example.com Robert firstname.lastname@example.org Robert '''
Each person must have a unique key or email address, but they can share the same value or name.
