The old limitations were 1000 tests in multitest and 25000 childs in one test. There are no more than 16 tests in multitests now. Tests were seriously updated (in fact only Test#1 and Test#2 were not changed). About 300 authors lost their AC after rejudge.

Good job. My previous solution was too slow. now I have AC.

I don't understand: my solution on Pascal is wrong now (stack-overflow), but my solution on C is AC as well as before test-updating... I will think about it... Maybe it's need just change stack size...
-------------------------
AC now. Only "{$M 16777216}" corrected my program.
(sorry for my bad english)

To JTim: You are right! First I have received Crash stack-overflow on 7 test, then I have added {$M 16777216} in my program and have received AC!

Very mysterious rejudge... My first CORRECT and FAST solution now gets WA #1. Or compilers have changed ever since???

Yes, Pascal compiler has changed since 2004, compiler options in your code are invalid now. Of course, your solution was not the aim of rejudge.
