I submitted problem HS12MBR, got 4 as result, then clicked on 4, which is a link to http://www.spoj.com/error/19272699. That page shows:
the text in the blue part (very dark) seems to refer to time limit exceeded.
Is anybody alive at SPOJ ? At least acknowledging the bug. Seems simple to reproduce...
We are alive. The problem you have mention used the feature which is no longer available. As for now, you will not be able to click on 4 to see the ugly prints.
