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.
