Nice work, both your methods work well. Do take a look at my notes regarding the Big-O. Let me know if you have any questions.

Since delete_at shifts all subsequent element left one index, it has a runtime of O(n). Using in your loop here gives you a method time complexity of O(n2)

If the strings are small yes, otherwise you can say O(n * m) where m is the min length of the strings.
