We have added new test to problem 1005. We do not want to
rejudge your submits. If you want, you can resubmit it to
make sure you solve it right.

I think there is a problem with this 1005. I have tried a
lot of test cases randomly generated by another program and
it works well. But, when I try to submit it, it says "Wrong
answer". Please see to it.
Thank you

I've tried a lot of test inputs also and it worked OK,
but then I've found a couple of examples when my
method does not work. I suppose your algorythm is
similar to my one. :)) Try to change it.

One of the "bad" examples is
5
16 13 7 6 4

The correct answer here is 0 (16+7=13+6+4). My first program
told the minimum is 2. :(
