Re: [Pharo-users] How to take care that the + before a number is ignored

You can do solve the problem without the "lines" variable but, believe me, you 
want to keep those lines in a collection.  It's gonna be a lot easier down the 
road!
Hint (to solve the problem) : look at what "lines" contain (instances of which 
class).  That class has everything you need to parse those '+2' and '-8' ...  ;)

| file  |

lines := OrderedCollection new.

file := StandardFileStream readOnlyFileNamed: 'day.1.input'.
[file atEnd] whileFalse: [lines add: file nextLine].
file close.
