back to boardwhen 6-th test is removed, the 7-th became the 6-th?? Posted by melkiy 10 Oct 2009 15:23 it's very important for understanding the condition! Re: when 6-th test is removed, the 7-th became the 6-th?? Posted by Yarik 10 Oct 2009 16:53 of course Re: when 6-th test is removed, the 7-th became the 6-th?? In fact it is not "of course"
And actually the only thing that makes it not ambiguos is sample test.
Many systems allow to have test numbers to be not consecutive. It makes possible to make funny tasks with the 1st test which is sample and 3112nd test, which is not, when person gets WA #3112 and thinks like "WHAT????!!!"
And the fact that tests on the competition in this task are consecutive is not obvious.
