i can convert a int by itoa()
i can convert a long by ltoa()
but how about long long?

It's alright, thank you very much
Actually i've just tried to use C++ and stream I/O instead of C
so i was not sure how to deal with EOF then

Problem 10469 is quite simple, but how would judge input the test number?
should i keep on reading until it terminate my problem anyway?
it hasn't been announced as a "multiple input"
