How do different data structures in Haskell affect performance?

In Haskell, the choice of data structure can significantly impact performance. For example, lists are simple but can be slow for random access, while arrays offer faster access times. Would you like to know more about specific data structures?

Yes, can you compare lists and arrays in terms of performance?

Sure! Lists in Haskell are linked lists, which means accessing an element by index requires traversing the list, making it O(n) in time complexity. Arrays, on the other hand, provide O(1) access time, but they have a fixed size and can be less flexible.

What about performance in terms of memory usage?

Lists are more memory-efficient for small datasets since they can grow dynamically, but they have overhead for each element. Arrays use contiguous memory, which can lead to better cache performance, but they may waste space if not fully utilized.

Are there any other data structures I should consider?

Yes, you might also consider using sets and maps, which are implemented as balanced trees in Haskell. They provide efficient searching, insertion, and deletion, making them suitable for different use cases.
