binary search tree

Hi,

I would maybe add for binary search trees that the O(log(n)) complexities are correct for the average complexities. For example if the tree has a "shape of a line" (every node has a child on the left : 10->9->8->7->6->5->4->3->2->1 then the worst case complexities will be O(n) ( search, insert, delete, access). If the values are deliberately written for the average complexities, then sorry for the disturbance :)

Kind Regards, Mark
