I like your test suite. Using large X forces a better solution.
Thank you Jonathan. I have discovered this philosophy thanks to James and @bmtran problems.
is there any mathematical algorithm that i dont know about to calculate such big range(10^13)?
i minimized my code as best as i can.still fails for such large number.
why i can't submit my solutions
