What is the difference between a map and a set in programming?
A map is a collection of key-value pairs, while a set is a collection of unique values without duplicates.
Can you give me an example of when to use a map?
Sure! Use a map when you need to associate unique keys with specific values, like storing user IDs with user information.
And when should I use a set?
Use a set when you need to store unique items and check for existence, like tracking unique visitors to a website.
Are there any performance differences between them?
Yes, maps generally have faster lookups for key-value pairs, while sets are optimized for checking the existence of items.
