Explanation:
Since we are talking about binary search, let's assume that the items are sorted according to some criteria.
Time complexity of binary search is O(logN) in worst case, best case and average case as well. That means it can search for an item in Log N time where N is size of the input. Here problem talks about the item not getting found. So, this is a worst case scenario. Even in this case, binary search runs in O(logN) time.
N = 700000000.
So, number of comparisions can be log(N) = 29.3 = 29.
So, in the worst case it does comparisions 29 times
Answer:
c. Dark Web
Explanation:
Surface web is also called visible web is a part of world wide web that can be easily searchable using search engines as its contents are indexed by the search engines such as Google and its contents are accessible by public using standard web browsers. So a is not a suitable choice.
