What are the differences between search algorithms?

Search algorithms are methods for finding specific data within a structure. Common types include linear search, binary search, and depth-first search.

Can you explain how binary search works?

Binary search works by dividing a sorted array in half, repeatedly narrowing down the search range until the target value is found or the range is empty.

What are the advantages of using depth-first search?

Depth-first search is memory efficient and can be implemented easily with recursion. It's useful for exploring all possible paths in a graph.

Are there any scenarios where linear search is preferred?

Yes, linear search is preferred for small or unsorted datasets where the overhead of sorting or maintaining order is not justified.
