I am sure (99.99%) that solved correctly Problem 100.
But the system said that my answer is wrong.
Could someone let me know if the system recognizes his\her solution as correct?
Thank you.

Re: Problem 100
I'm not posting solutions here. Just need help.
My initial solution was rejected.
It was b = 707106788769 | N = 1000000010723 which is closer to 10^12.
My b is also smaller than the b in the solution.
b * (b-1) / N / (N-1) == 0.5 holds too.
Am I missing something?!
I'm super confused...

Re: Problem 100
This does not precisely hold for those values of b and N. It's close, though: the discrepancy is so small that 64-bit floating point arithmetic would not detect it.
