Kpadma, please note that the question is about the DIFFERENCE BETWEEN THE FIRST AND THE LAST NUMBER not the other way round.
Yes, you've a point. I've also noticed that issue, when I solved the problem.
But, Is it not true that the difference between two number is always postive
or zero. For exampble, "difference between A and B" is | A - B |, whereas
"A exceeds B" is A - B.
I could be wrong, so it is worth clearing up this confusion.
Dear Praetorian or Akamai,
Could you help us with this issue?
