Functions

func InputFile

func InputFile() io.Reader

InputFile returns an io.Reader for the file pointed at by the --input flag. If the flag is not specified, it looks for a file named "input.txt" in the same package as the caller.

func Ints

func Ints(r io.Reader) iter.Seq[int]

Ints returns an iter.Seq[int] over all lines in the provided io.Reader, converting each line to an int. This method panics if conversion of any line fails.

func Lines

func Lines(r io.Reader) iter.Seq[string]

Lines returns an iter.Seq[string] over all lines in the provided io.Reader.

func Sections

func Sections(r io.Reader) iter.Seq[string]

Sections returns an iter.Seq[string] over all blocks of lines in the provided io.Reader. Blocks of lines have at least one extra newline separating them.
