Has anyone gotten this one to work using Java?
It looks like the judge is running a lot of input through this one, and I am timing out.
I've tried a whole slew of different stream readers.
I'm thinking about trying NIO next...

Yes people have solved it using Java.
Try using BufferedReader and BufferedWriter.
Check input and AC output for thousands of problems on uDebug!

Thanks for the response!
I had already actually tried that.

It turns out the bottle neck was not in reading the inputs.
It was in Java's printf() implementation.
I rolled my own hex formatter and just got accepted.

Learn something new everyday... :)
