Greedy binary tree
WebAlgorithms have been found that construct nearly optimal binary search trees. The weighted path lengths of such trees cannot differ by more than a constant factor from the … Web1 Of course it depends if you are making efforts to keep the tree balanced (e.g., AVL, RedBlack, Splay, randomized binary search trees). O (n log (n)) is worst case for AVL and RedBlack, average case for randomized BST's, and amortized case for Splay. If sorting is your goal, a heap would be preferred over BST which gives O (n log (n)). – wcochran
