Meta Stack Exchange is where users like you discuss bugs, features, and support issues that affect the software powering all 157 Stack Exchange communities.

What is meta?
Here's how it works:
  1. Any Stack Exchange user can ask a question
  2. The community provides support, votes on ideas, and reports bugs
  3. Your voice helps shape the way Stack Exchange operates

There's currently a lot of mistagging and overlap related to (and ), and .

The goal:

  • should be used to refer to questions specific to BSTs (not binary trees in general)
  • should be used to refer to non-BST binary trees.
  • should be used to refer to non-binary trees.
  • should not be used to refer to binary trees at all.

My reasoning:

  • All BSTs are binary trees, so tagging a question with both and or is redundant.
  • Similarly, all binary trees are trees, thus using both and is redundant.
  • currently refers to binary numbers, it should not be used for binary trees as well.

Useful searches:

(there's probably a bit of overlap in the above searches and they may not be 100% exact)

Not all of the questions in these results are necessarily bad - some questions may ask about both binary trees and trees in general, or about differences between the different types.

Additional notes:

Note that because the question is asking about a BST doesn't mean it's specific to a BST - finding the depth of a BST is the same as finding the depth of regular binary tree, thus should be used there, not .

And there are plenty of questions that say binary tree (and probably many that are also tagged as such) but actually mean BST.

Ideally all questions tagged with , and should be reviewed.

There issue is likely to creep up again. It might be wise to put a note in each of the tag excerpts. And perhaps rename (any suggestions?).

I've already done a fair amount of retagging with regard to this.

It's a valiant effort, but for little benefit. – Robert Harvey Oct 21 '13 at 0:01
@RobertHarvey It might not be high on the list of things that needs to be done, but it's still on the list. binary -> binary-tree is probably the most significant part of this. – Dukeling Oct 21 '13 at 0:31
