To build:
make
To run:
./prog
Try:
cat prog.c
./prog | diff - prog.c
Judges' remarks:
At this point you might be wondering, WTF?*
* What The Freak (polite form)
* What's This For? (you may be wondering)
* What the Fish (python form)
How is this code obfuscated? Well look again:
less prog.c
more prog.c
Where did those underscores come from? Well RTFS!**
** Read the Freaking Source (polite form)
** Read The Freakin' Screen (polite form)
If you are still puzzled, look at prog.c with your favorite text editor.
Author's remarks:
Follow this instruction literally!
cat prog.c
gcc -w -o prog prog.c
./prog
You will do a double take.
Hint 1: Do less prog.c. You will see an emphasized string if your
terminal supports bold.
Hint 2: Do wc -c prog.c. This is very long one-liner.
Spoiler: Open the source with an editor like vim or emacs.
