Thanks for the info. Fixed. Seems spoj.pl is down. |

@Piotr: I found the reason for failure. Math.factor() only does trial divison by the first 1024 primes! Also note that all links on the SHORTEN pages which starts with spoj.pl has stopped working. On the Links page, the RSS feed, etc. |

I made a rejudge after adding a test with some small numbers. Feel ashamed for not checking boundary cases, sorry. |
