What are some real-world use cases for different data structures?

Data structures are essential for organizing and managing data efficiently. For example, arrays are great for storing lists of items, while linked lists are useful for dynamic data where size can change.

Can you give me specific examples of where I might use a hash table?

Sure! Hash tables are commonly used in situations where quick lookups are necessary, like implementing a database index or caching data for fast retrieval.

What about trees? When should I use a binary tree?

Binary trees are ideal for hierarchical data representation, such as file systems or organizational structures. They also enable efficient searching and sorting operations.

Are there any scenarios where a stack would be preferred?

Yes, stacks are perfect for scenarios that require backtracking, like undo mechanisms in applications or parsing expressions in compilers.
