Is it incompletely described? Or it is me? [problem from another OJ]

Revision en2, by aboAdnan, 2017-12-31 17:15:23

Hello everyone!

Yesterday I read this problem (https://a2oj.com/p?ID=3), and after that, it shows to me that there were waste of some information that the solver needs to solve it.

But, surely, several unaccessible accepted submissions, made me incline to accuse my understanding.

So I, thankfully, hope you to help me in this problem.

After you read the problem statement, see this please:

Is there, in the statement, any expression describes the way to construct the expansion string of the poly-line ( initial ) string? I saw that there is not. But according to the examples, not all of the way to construct the expansion string is accepted!!. Thanks in advance.
