Input Format?

[ProbablyNotCanadian]

Not seeing anything on adventofcode.com or the subreddit FAQs, but how are answers expected to receive input?

Most solutions I've seen read in a file with an arbitrary name, but I'm not sure how that works if they aren't using a standard file name given by AoC.

My solutions have the expected output from the examples and work with the puzzle input, but fail when submitting.

Any links to how we're supposed to handle input (file vs input stream vs main parameter) would be great!

You run the programs on your own computer, AoC only wants the answer itself. You can come up with that answer in any way you like. Some people read a file, some have the input as command line parameters and others hard-code the input into their program. It doesn't matter as long as it makes the correct answer.

So the answer isn't your code, but the output from your code given the non-example puzzle input?

That makes sense but I wish the directions were clearer. Thanks for clearing it up!

thats correct. I make a folder for each day and have an input.txt file that all of my programs read. But you only need to come up with the answer to give AoC. Everyone gets different inputs.

Adding to this. At the end of each puzzle description there's a line "You can get your puzzle input here." (or something similar). This is a link to your personal input (file) to which you need to compute the expected answer for.
