I try to use brute force to caculate all possible arrangement, but I just can't get AC on this porblem. So, could anyone please give me a hint?

Besides, there seems to be some illegal input given, and how should I handle with them? Skip all the four line? Or skip only one line?

Um... I found another mistake in my code...and just got AC

Anyway, thank you very much.

It said:
In writing the decimal expansion, enclose the repeating cycle in parentheses when possible. If the entire repeating cycle does not occur within the first 50 places, place a left parenthesis where the cycle begins - it will begin within the first 50 places - and place ``...)" after the 50th ...

I'm so sorry...
It seems that I asked a stupid question again...
but...I chganged the two places you mentioned...

I still got WA...

I really have touble with this prob...
I don't know why I keep getting WA :(
