... In the class we have seen an implementation of AVL tree where each node v has an extra field h, the height of the sub-tree rooted at v. The height can be used in order to balance the tree. For AVL trees with n nodes, h=O(logn) thus requires O(loglogn) extra bits. 1. How can we reduce the number of e ...
