One of the issues I run into every couple of weeks with Erlang is distinguishing lists from strings.
This is made complicated because strings are merely a list of integers. That said, running with
that definition, there is a very simple solution.
Admittedly, not an efficient solution. You could wrap it in a try-catch block and use a throw to exit the loop upon reaching the first
non-integer, but the worst-case efficiency remains O(N). Any suggestions on how to improve?
