Day 4

Part 1

I keep not learning. RTFM.

I started happily recursing into snakes of XMAS letters, only to realise that only linear words are requested. Simple loop then.

Part 2

Also quite easy. At first i messed up the cross, as i was checking for every angle, not only 45. And i had an error in the inverse of the direction of the cross, but nothing to hard.
