pb10000 - WA instead of PE

[vpanait]

Hello,
in my humble opinion, pb10000 - longest path in a DAG, has a small issue.

Problem states "Print a new line after each test case.", however if the last "\n" is omitted it reports WA, instead of PE.

That's not unique to problem 10000, don't count on getting PE on any problem, extra or missing whitespace often results in WA.

New blanklines result in Wrong Answer. After all, they go against the specification....
