Answer:
B.O(2n)
Explanation:
The time complexity of solving towers of hanoi problem recursively is O(2n) because there are two recursion calls in the solution of tower of hanoi.First recursive call to move n-1 disks to from source to helper then the user moves nth disk from source to destination after that recursion moves n-1 disks from helper to destination using source as helper rod.So each recursive call make two more recursive call this makes the time complexity be O(2n).
I'm unsure in What it is you're asking.
While their rational of a drug user's mind???
this alone makes no direct sense.
also I'm unsure what Computers and Technology have to do with drug user's or their brains.
I can leave you with this a drug addict is and addict hence the name it's an addiction so there is no rationality or distinctiveness in knowing not to use again until one truly wants to get help and change for the better of self.
hope this helps
