What are the best data structures for handling large data sets?

For large data sets, some of the best data structures include hash tables, trees, and graphs. Each has its own advantages depending on the use case.

Can you explain why hash tables are effective for large data sets?

Hash tables provide average-case constant time complexity for lookups, making them very efficient for large data sets where quick access is crucial.

What about trees? When should I use them?

Trees, especially balanced trees like AVL or Red-Black trees, are great for maintaining sorted data and allow for efficient range queries.

Are there any specific scenarios where graphs are preferred?

Graphs are ideal for representing relationships and networks, such as social networks or transportation systems, where connections between data points are important.
