How do data structures affect algorithm complexity?

Data structures play a crucial role in determining the efficiency of algorithms. They influence both time and space complexity.

Can you give an example of a data structure that improves performance?

Sure! For instance, using a hash table can significantly reduce the time complexity of search operations to O(1) on average.

What about trees? How do they compare?

Trees, especially balanced ones like AVL or Red-Black trees, can provide O(log n) time complexity for search, insert, and delete operations, which is efficient for sorted data.

Are there scenarios where a simpler data structure is better?

Absolutely! Sometimes, simpler structures like arrays or linked lists can be more efficient for specific tasks due to lower overhead.
