WebThe Binary Search — Problem Solving with Algorithms and Data Structures using C++. 6.4. The Binary Search ¶. It is possible to take greater advantage of the ordered vector if we are clever with our comparisons. In the sequential search, when we compare against the first item, there are at most n − 1 more items to look through if the first ...

WebThe major difference between the iterative and recursive version of Binary Search is that the recursive version has a space complexity of O (log N) while the iterative version has a space complexity of O (1). Hence, even though recursive version may be easy to implement, the iterative version is efficient.
