Hi cyberfish, 7 minutes is much too long. It obviously shows that your algorithm need to be optimized. I used to try such an slow algorithm. I am not fortunate as you, my notebook is so old that if its CPU 100% occupying keeps more than 30 seconds, it must breakdown at once. So I have to figure out a better algorithm. Fortunately, I succeed after all.
Anyway, as a summary of all important algorithm contests, any digital problems should not to be programed like for(i=0; ...;i++). Wish you succeed. Good luck everyone!
