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.

@Piotr: for what input is my latest Pike submission (#11149257) wrong?

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

Number of test cases was reduced to 100.

I changed time limit from 10 to 15 sec. ;) // And from 15 to 20. :) Last edit: 20100518 07:31:52
