# Using another answer's improvement in your own answer

Hypothetical scenario:

Person A writes a review for a question. He writes a improvement X. Person B also writes a review for the question, after person A does. Person B has something to add to improvement X and uses (for example) the new function from the improvement that person A wrote.

My scenario:

This question was answered by Ethan Bierlein. I wrote an answer for it too, but I used a function that Ethan wrote in his answer in my answer.

Is this sort of thing okay, or should I have left a comment to Ethan's answer as something he could add to his post?

This is acceptable and happens quite regularly. To be honest, I'm always glad when it happens.

Take a look at the following answers for example. Here, @glampert (person A) posts an answer in which he mentions multiple good points. In one of the next answers, here, @Edward takes one of those points and elaborates it further. Both answers are very valuable.

• I'm sure there have been meta questions about this topic before, I just can't find them. – Mast Jul 3 '15 at 18:59

It's perfectly ok to post answer that contains a point from another answer, with some improvements added, if you give credit to the user you're borrowing from.

It can be as explicit as:

... as @abc mentioned in his answer...

Or as subtle as:

... in addition to using a Map instead of a List (thanks @abc!)...
