What are the complexities of different search algorithms?

What are the complexities of different search algorithms?

The complexities vary by algorithm. For example, binary search has a time complexity of O(log n), while linear search is O(n).

Can you explain why binary search is faster than linear search?

Binary search is faster because it divides the search space in half with each step, while linear search checks each element sequentially.

What about depth-first search and breadth-first search?

Depth-first search has a time complexity of O(V + E) and is memory efficient, while breadth-first search also has O(V + E) but uses more memory.

Are there any other search algorithms I should know about?

Yes, algorithms like A* and Dijkstra's are important for pathfinding and graph traversal, each with their own complexities.
