• Tree rotation — A tree rotation is an operation on a binary search tree that changes the structure without interfering with the order of the elements. A tree rotation moves one node up in the tree and one node down. They are used to change the shape of the tree …   Wikipedia

• Binary tree — Not to be confused with B tree. A simple binary tree of size 9 and height 3, with a root node whose value is 2. The above tree is unbalanced and not sorted. In computer science, a binary tree is a tree data structure in which each node has at… …   Wikipedia
