What are the differences between search algorithms?

There are several types of search algorithms, including linear search, binary search, and depth-first search. Each has its own strengths and weaknesses.

Can you explain how binary search works?

Sure! Binary search works on sorted arrays by repeatedly dividing the search interval in half. If the target value is less than the middle element, it narrows the interval to the lower half; otherwise, it narrows to the upper half.

What are the time complexities of these algorithms?

Linear search has a time complexity of O(n), while binary search has a time complexity of O(log n). Depth-first search can vary but is generally O(V + E) for graphs.

Which search algorithm is the most efficient?

It depends on the context. For sorted data, binary search is very efficient. For unstructured data, other algorithms like depth-first or breadth-first search may be more suitable.
