The key question
is "what do you mean by improve"?
I'd start by
asking "what are you doing that you will still have to do
in
part 2, and what
won't you do?"�� So looking at part 2, you will want to
convert the lines
to integers, and
�� input := Array
streamContents: [:lines |
�� �� 'input.txt'
asFileReference readStreamDo: [:in |
�� �� �� [in atEnd]
whileFalse: [lines nextPut: in nextLine asInteger]]].
gives you a chunk
of code you can use in both parts.�� So you might
want to have
Day1
�� changesFrom:
aFileName
�� �� ^Array
streamContents: [:changes |
�� �� �� aFileName
asFileReference readStreamDo: [:in |
�� �� �� �� [in atEnd]
whileFalse: [changes nextPut: in nextLine asInteger]]]
�� partOne:
aFileName
�� �� ^(self
changesFrom: aFileName) sum
�� partTwo:
aFileName
�� �� ...
The file name
should not be wired in because you want some test files.
