A balanced binary search tree where the height of the two subtrees (children) of a node differs by at most one. Look-up, insertion, and deletion are ''O(log n)'' (see [BigONotation]), where ''n'' is the number of nodes in the tree. |

This is done by keeping a value in each node of the tree which is equal to it's height. (ie: for leaf nodes it's 0, for nodes above them it's 1, nodes above them 2 and so on). |

When you insert a new node, you see if this makes one subtree off an internal node longer than the other and if so do a rotate so that they are equal again. |
