Ever been in a situation where you were in an interview, and realized immediately afterwards (after the nervousness wore off) that you did something wrong?

I had a phone interview today. I was asked an n-ary tree problem, and coded an algorithm that used a space overhead, then a different algorithm with no space overhead. However, my solution was inefficient, since I traversed the tree top-down rather than bottom-up.

The interviewer said I did a good job, but I'm still wondering if he noticed and marked down for my choice of implementation. Should I follow up with an email correcting myself, or just let it and avoid making things worse?
