Unbalanced Trees

If items are added to a binary tree in order then the following unbalanced tree results:

. The worst case search of this tree may require up to n comparisons. Thus a binary tree's worst case searching time is O(n). Later, we will look at red-black trees, which provide us with a strategy for avoiding this pathological behaviour.

Key terms
