Well said, BrowserUk. Maybe I should just try Project Euler instead :P
I learned a lot from all your responses and concluded that this is an obvious demonstration of how good you guys are at perl and how devoted you are to solving a problem. Giving a ++ to all of you
Comment on Re^4: Sorting challenge (Insertion sort)
Project Euler's challenges are at least usually well thought out, and you're unlikely to get rejected with reasonable code that should pass. But some of them can consume a fair amount of time on research, and that time might be better spent productively. ;)
