What do you consider "much larger"? A hundred lines? A thousand? A million? A billion? A simple solution may scale from 12 to 1000, but perhaps not to a million and beyond.
It would be a shame for someone to waste their time crafting code that can never be used because it takes forever to complete or because it requires more memory than the system has available. So, please, be more precise than "much larger". Also, if the file can approach the size of your system's memory, you should definitely mention that.
