DDOS of adventofcode.com, did not get to open the
puzzle until 06:05 (five minutes local time).
Screwed up the zip() and lost valuable minutes by
trying to replace it with itertools, only to find
I have made a typo (did AB CD EF instead of AB BC
CD).
I also lost valuable minutes by tring to solve p1
with one nested loop. Stupid.
For part 2, I created the issafe() helper to be
able to remove items from reports and test, one
at the time.
Realized afterwards I got the ints() helper, so
original code before cleanup splitted the input and
mapped all words with int(). valuable seconds lost
there.
Also, collections.Counter() was used initially since
I was too tired to remember count() method in lists.
Line 8 took the longest time to figure out. A typo
took 1-3 minutes to find for part 2.
Form: Sleep deprived, felt slow.
