What are the different types of data structures and their uses?

There are several types of data structures, including arrays, linked lists, stacks, queues, trees, and graphs. Each has its own use cases.

Can you explain how a binary tree works?

A binary tree is a hierarchical structure where each node has at most two children, referred to as the left and right child. It's used for efficient searching and sorting.

What are the advantages of using a hash table?

Hash tables provide fast data retrieval, with average time complexity of O(1) for search, insert, and delete operations, making them ideal for scenarios requiring quick access.

How do stacks and queues differ?

Stacks follow a Last In First Out (LIFO) principle, while queues follow a First In First Out (FIFO) principle. This affects how elements are added and removed.

Can you give me an example of when to use a graph?

Graphs are useful for representing relationships, such as social networks or transportation systems, where you need to model connections between entities.
