Interesting contest, quite educational and meaningful for beginners.

But D may be too easy for its place, it's a traditional maths problem which is far more easier than C.

    Thanks for your opinion, Actually we know it's easy, But many people couldn't come up with the easy solution during the round (if you see standings) Also some of our testers couldn't come up during testing too, So we decided to put it at position D.
