Why WA on Fibonacci String problem?

#1

Hello Everybody!

I’m solving Fibonacci String problem, and this is my last submission that got WA. Please, tell me why I’m getting this verdict, because I have not yet got what’s the wrong in the submission.

Thanks in advance.

I have found the issue.

I was testing just the sorted permutation of f© values:

f(c1) <= f(c2) <= f(c3) <= … <= f(c|C|).

But, one also have to test this permutation:

f(c2) >= f(c1) <= f(c3) <= … <= f(c|C|), where f(c2) is the second minimum value among them.
