Question

Quizplus · Accepted Answer

The maximum number of steps needed for a binary search is log(base 2) n. In this case, n can range from 4 to 7, so the maximum possible value of log(base 2) n is log(base 2) 7, which is approximately 2.8. Since we can't have a fractional number of steps, we round up to the nearest integer, which is 3. Therefore, the maximum number of steps needed for a binary search in this scenario is 3.
