Its crazily obfuscated .
What kind of tools he might have used for this ?
Is he cheating and this is done to avoid plagarism?
Is obfuscation like this is allowed in codechef ?
to be very honest I really can’t tell that this guy is actually cheating or not but he definitely is using a lot of macros and getting the solutions ! even checked this persons practice solutions , being a 5 star coder (if he is legit ) is solving easy problems which are below 1200 (at least some of them ) .
