WebWhen the binary tree gets skewed, the running time complexity becomes the worst-case scenario i.e O(n) but in the case of the AVL tree, the time complexity remains O(logn). Therefore, it is always advisable to use an AVL tree rather than a binary search tree. Remember that every AVL Tree is a binary search tree but every Binary Search Tree … Web4.7K. 163. Companies.

A simple parallel implementation breaks the master list into k sub-lists to be bin-searched by parallel threads. The resulting worst-case time for the binary search is log_2(n/k) realizing a theoretical decrease in the search time.

WebBinary Search Tree (or BST) is a special kind of binary tree in which the values of all the nodes of the left subtree of any node of the tree are smaller than the value of the node.
