What are the best data structures to use for algorithms?

The best data structures depend on the algorithm and the problem you're solving. Common ones include arrays, linked lists, trees, and hash tables.

Can you explain when to use a hash table?

Hash tables are great for fast lookups, insertions, and deletions. Use them when you need to store key-value pairs and access them quickly.

What about trees? When should I use them?

Trees are useful for hierarchical data and when you need to maintain a sorted order. Binary search trees, for example, allow for efficient searching.

Are there specific algorithms that work better with certain data structures?

Yes, for instance, quicksort works well with arrays, while breadth-first search is typically implemented using trees or graphs.
