Please explain the thinking behind the hint in this problem.
If you look at my attempt it looks logical to me yet it is not logically correct. How do you see modulo and division symbols as a method to this problem.

I don't understand what's wrong this time
So I've made it so I'm not removing from the loop I'm iterating through in addition to adding a nested loop that removes if the string is the same. How would I go about fixing this? I believe I'm on my 10th or so attempt.
