Sometimes I stumble upon follow-up questions, where code is being posted again after having gone through a review (or two). 

Examples of possible sets of follow up questions:

- [Find missing numbers](http://codereview.stackexchange.com/questions/35902/find-a-missing-numbers-single-missing-number-and-two-missing-numbers-from-cons) - [Find even more missing numbers](http://codereview.stackexchange.com/questions/36031/find-two-missing-elements-from-a-sorted-array-in-given-range) - [Even more missing numbers](http://codereview.stackexchange.com/questions/36117/find-missing-numbers-in-a-range-when-a-sorted-array-with-two-elements-with-rang)
- [Binary search tree](http://codereview.stackexchange.com/questions/31994/creating-a-binary-search-tree) - [Another binary search tree](http://codereview.stackexchange.com/questions/31998/create-a-binary-tree-code-review-request)
