What are the differences between search algorithms in C++?

What are the differences between search algorithms in C++?

There are several search algorithms in C++, including linear search, binary search, and hash-based search. Each has its own use cases and performance characteristics.

Can you explain how binary search works?

Binary search works by dividing a sorted array in half to find a target value. It repeatedly narrows down the search range until the value is found or the range is empty.

What is the time complexity of linear search compared to binary search?

Linear search has a time complexity of O(n), while binary search has a time complexity of O(log n), making binary search more efficient for large datasets.

Are there any other search algorithms I should know about?

Yes, you might also want to explore depth-first search (DFS) and breadth-first search (BFS), especially for graph data structures.
