what is the solution to the problem C Golf Bot
Fast Fourier Transform :) though 1 of the 2 that solved it during SWERC, did O(n^2) with a very small constant (I think they used int's as bitmasks)
That's true. Our priority was to make it fair between C/C++ and Java, but -O2 and bitwise operations are a killer.
Are you competing this year?
Yes, I am, with angargo (as last year) and albertnez, new member of UPC-1; dirbaio reached the 2 WF limit last year.
Cool, I'll see you there then :)
Good luck!
