Guys, can u help me what's wrong with my code? I have been tried 15 times nothing changed still WA.

Also I'm new to UVa can someone tell me how its handle the newline character. I mean when its safe to left the last line with \n and when it is not
Thx

[brianfry713]

Always print a newline char at the end of the last line.
