We've written a small but useful extractor tool to help with extracting test cases from ref/inputs.
Its cmdline is:
This way it's easy to copy&paste output from your solution into it.
are the ref/input start and last index using base1 (ie the reference output format)
is used to create _ref.txt and _input.txt as output files.
adds a border, eg - + is written out for the reference part
specifies the sequence to use from all sequences
If is not found, all possible input sequences are dumped to help you choose the right one.
Hope it's useful :)
