How can I use data structures to reduce memory usage in my application?

You can use efficient data structures like arrays, linked lists, or hash tables to minimize memory usage. For example, using a linked list instead of an array can save space if your data size varies.

What are some specific data structures that are memory efficient?

Some memory-efficient data structures include tries for storing strings, bloom filters for set membership, and sparse arrays for large datasets with many empty values.

Can you explain how a bloom filter works?

A bloom filter is a space-efficient probabilistic data structure that tests whether an element is a member of a set. It can produce false positives but never false negatives, making it useful for applications where memory is a concern.

Are there any trade-offs when using these data structures?

Yes, while they save memory, some structures like bloom filters can lead to false positives, and others may have slower access times. It's essential to choose based on your application's needs.
