I'm also having problems with WA, I tried all the input samples and some that I found in this forum... and a lot more... and it was always OK.

Do you have more input samples?

When you have a good reply (I know that i didn't help you, but), could you let me know?

Thx,
Carlos

I know it's a simple problem, but it always say WA...
I tried all special case in this Forum...
Is there more special case???

Someone could help me... thx!!!
