What are the best data structures for specific tasks?

What are the best data structures to use for searching and sorting data?

For searching, hash tables are great for quick lookups, while binary search trees are effective for sorted data. For sorting, arrays or linked lists can be used, depending on the algorithm.

What about when I need to implement a queue?

For a queue, you can use a linked list or an array. A linked list is often preferred for dynamic sizes, while an array can be more efficient for fixed sizes.

Are there specific data structures for graph-related tasks?

Yes, for graph-related tasks, adjacency lists and adjacency matrices are commonly used. The choice depends on the graph's density.

What data structure should I use for implementing a priority queue?

A binary heap is typically used for implementing a priority queue, as it allows for efficient insertion and removal of the highest (or lowest) priority element.
