"The solutions and answers provided on Experts Exchange have been extremely helpful to me over the last few years. I wear a lot of hats - Developer, Database Administrator, Help Desk, etc., so I know a lot of things but not a lot about one thing. Experts Exchange gives me answers from people who do know a lot about one thing, in a easy to use platform." -Todd S.

You should clarify...what KIND of binary tree?

A "binary tree" is simply one where nodes have no more than two children.

A "binary search tree" (BST) is ORDERED and has rules on how nodes are inserted.

An AVL tree is a self-balancing BST that has additional rules on the difference in depth between two child nodes.

Here's an interactive tree that you can actually see what will happen when those sequences are entered into a standard BST:

I've done this stuff before.  Just has been  while.

A binary search tree.  1, 2, 3 would give:   root is 1, right child of 1 is 2, right child of 2 is 3, correct?

6, 5, 4 would give:   root is 6, left child of 6 is 5, left child of 5 is 4, correct?

That's correct.  Those two sequences are probably for demonstrating that a standard BST is no better than a linked list when the data being inserted is ALREADY SORTED.
