I wasn’t too sure when you suggested renaming the suffix. I assumed you meant renaming this file suffix to `.input` to match the other file, so I did that. However, if you intended for a different suffix, like `.data` or something else, I can make that change. Please let me know if you have a specific suffix in mind.
