When testing your testing mashine adds additional KBs to
the memory used by the program it's testing.That's very
unpleasent because programs that use less memory than the
maximum for a particular problem are judged "Memory Limit
Exceeded".So please tell me how many additional KBs does
the testing machine add or change the maximum memory for
the problems.
P.S. I got really irrated while trying to solve 1100.My
program used 900KBs but the testing machine said 1011KBs.

It doesn't depend on testing software. Actually, it depends
on compiler - memory used for variables, stack and other
things. Usually, there is enough memory to solve problem,
although problem designed in such a way, that wrong
solution hits memory limit.

Your solution was interrupted than it allocated more than
1000Kb. It doesn't mean, that 1011KB is enough for your
program. If program could continue running, it allocated
more.

Being author of 1100, I can say that without memory limit
this problem become to simple and boring.
