What are the different types of collections in programming?

In programming, collections are data structures that hold multiple items. Common types include arrays, lists, sets, and maps.

Can you explain the performance differences between these collection types?

Sure! Arrays have O(1) access time but O(n) for insertions. Lists allow O(1) insertions but O(n) access. Sets offer O(1) average time for lookups, while maps provide O(1) for key-value pairs.

Which collection type is best for large datasets?

It depends on the operations you need. For frequent lookups, sets or maps are ideal. For ordered data, consider lists.

Are there any trade-offs I should be aware of?

Yes, each type has trade-offs in terms of memory usage, speed, and ease of use. It's important to choose based on your specific needs.
