Re: Algorithms
Good try! So it is O(N log N) now. Can we do better?

If it is troublesome, then why do you bother writing the solutions?

Yes, good job
By the way, you can also do it by induction (proving the AM-GM implicitly I guess )

Re: number of common divisors
For posts of such kind, please provide a brief description of the main idea of your algorithm and don't post your code unless absolutely necessary (e.g getting wrong answer, well even in that case people usually post ideas because most of the time wrong ideas are the reason for wrong answer). In mos...

Re: Algorithms
@Hadaram: Here. I guess you probably already know this. Let me repeat again -- "Algorithm is a creative process. You will go nowhere near to achieving competency in algorithm design by trying to "understand algorithms" better." So I suggest a better way can be try to solve a problem. If you are stuc...
