Hi,
This is the first time I have come to SPOJ.

I was wondering how do I give input and print Output for codes for SPOJ.
I use C.

Do I use scanf , printf, etc.?
Or do I read a text file and write to a text file ?

What exactly is the way.

Will be great if you can give me an example solution to any problem ... Just the input / output part will be enough ....

Thanks in advance,
Vineet
