I solved B but i'm interested how did you guys solve it??

No it's running.

Consider swapping xi and vi. I was only checking if the bone is at Xi so I move it to Vi. I wasn't checking if it is at Vi.

I can't forgive myself for wasting too much time to find out why was my B solution failing at test 3 ..

That was fast.

Nice picture.

codeforces really needs to scale up to handle more users.

B hack?

Codeforces really needs to scale up to handle more users.

Yeah that's what I thought, Thank you.

Div2 B hack?

How to solve C?

Why is molly holy?

problem B

Word is a maximal sequence of consecutive letters, i.e. such sequence that the first character to the left and the first character to the right of it is an underscore, a parenthesis, or it just does not exist.

I though it here refers to the word not to the underscore or the parenthesis.. which cost me 3 WAs and a lot of time ..

ohh.. Thank you..

Can you explain a little bit more please?

My B solution got hacked, What would be the problem with that code? http://codeforces.com/contest/721/submission/21032401

problem B hacking Test Case please?

The next n lines contains passwords, one per line — pairwise distinct non-empty strings consisting of latin letters and digits.

I got hacked for it

let's wait and see how many div2 B solutions will fail at test n = 1

Don't even bother replying him.

I believe that is caused by the extra space at the end.

Let us be able to practice please.

Isn't the answer of that

Hacking test of B?

I feel I'm the only Idiot who thought there will be a case where I should print "Impossible" in B ..

Are the problems suitable for both divisions?

We hope so!
