Re: Problem 127

Please don't post solution code.

If your code is slow, but still works, then there's no need to ask here: use the solvers' forum for problem 127.

Re: Problem 251

You seem to be under the impression that negative numbers can't have real cube roots :-o

Re: C++ huge boolean vectors

Does putting "static" in front of "vector" help?

Re: Problem 247

From S 2 you can draw a line from that meets the y-axis and goes through S 12 for example. I assume you mean the shortest line though which must then be perpendicular to the y-axis and parallel to the x-axis. A quicker way of saying "perpendicular to the y-axis and parallel to the x-axis" would be ...

Re: Problem 247

Draw a horizontal line from (anywhere inside) S2 to the Y axis. How many squares do you cut through? Just one.

That's the sense in which we mean "to the left".

Re: Problem 243

R(d) is the number of resilient proper fractions, divided by d-1.

"Proportion" would have been a better word than "ratio".

Re: Euler forum

Our current approach to this is to produce those PDF files you see in the right-hand column of http://projecteuler.net/index.php?section=problems (at least for the earlier-numbered problems). One constraint imposed upon us is access control: the PDF should be available only to those who have solved ...

Re: Problem 238

OK, there was a mistake. We're on the case. We hope to release a revised (and correct) version of the problem soon.

Thank you for drawing this to our attention.
