Part1:

$ elixir day2part1.exs

Thoughts:
|
||
|
|
|
||
|
|
Use a regex to parse the input
|
||
|
|
Huh, can't iterate a string with Enum. Split into a list with Enum.graphemes/1

Thoughts:
|

|
|
|
||
|
|
Convert indices to be zero-based.
|
||
|
|
No xor operator without importing Bitwise? Just write it manually.
|
||
|
|
Initially misread the problem - thought first position must match, and second position must not match,
|
||
|
|
which caused some confusion.
|
||
|
|
Probably rebound to the same variable names a bit too much - should work on clearer variable names.
