I didn't expect there to be another puzzle where we had to split on emptylines agian. I guess I should have made that SplitOn{} I was thinking about

[adamratzman]

I just used \n\n again 😄

[bjonnh]

I mean that's fast and you don't have to remember what you named your function

[Kroppeb]

Yeah but I get my input as a list of strings

[Kroppeb]

I guess I have a function that returns a string

[Kroppeb]

But using \n\n wont work on windows, so idk

[bjonnh]

why do you get your input as a list of strings?

[Kroppeb]

[adamratzman]

\r\n\r\n @Kroppeb

[Kroppeb]

because I have a bunch of functions that parse the inputs

[bjonnh]

I have two helper functions textFile(filename) and linesFile(filename) that give me either the file as a full text, or lines

[Kroppeb]

well my solution is shorter

[bjonnh]

you can probably tell intelliJ or whatever your editor is to use \n for line returns

[bjonnh]

so when you make the file you get \n

[Kroppeb]

although i use curl to download my input

[bjonnh]

so you should have \n then

[Kroppeb]

Lost about 30 points a year ago because intellij droped the ending whitespace

[Kroppeb]

See i don't want to have to think about line endings

[Kroppeb]

And split on might be useful for other things too

[bjonnh]

sure sure

[bjonnh]

I'm not a windows person so that's not something I really care about

[bjonnh]

but I should keep that in mind with windows users sending files around

[adamratzman]

good points

[Kroppeb]

anyway, with reduce and splitOn, i now have a "oneliner" for each day

[Kroppeb]

part 2 uses * instead

[Kroppeb]

.e() converts to a List<Char>

[bjonnh]

oh I was going to ask

[bjonnh]

why do you need that?

[Kroppeb]

you can't convert a string to a set

[Kroppeb]

oh

[Kroppeb]

ok, intellij was autocompleting too slow so i thought you couldn't

[bjonnh]

great I'm stealing your sumby

[bjonnh]

never think about that one

Go with sequences my friends 🙂
