HINTS AND RULES
RULES:
The only rule is not to cheat, that's it i guess.
HINTS:
Level 1: Just follow the instructions. Stuck at the last one? Do it with STYLE.
Level 2: Remember the trick you used to get the third digit in level 1?
Level 3: That's a weird number of lines in the code, isn't it?
Levels 4-7: You're on your own! Goodluck!
