WebApr 5, 2024 · The quantity of edges connecting the root node and the farthest leaf node makes up the height of a binary search tree (BST). The deepest node in the tree's hierarchy can be thought of as its depth. The height of a BST can be used to determine the complexity of certain algorithms that work with the tree, such as search and insertion. WebAug 9, 2024 · First, we have to find two end vertices of the diameter and to find that, we will choose an arbitrary vertex and find the farthest node from this arbitrary vertex and this node will be one end of the diameter and then make it root to find farthest node from it, which will be the other end of diameter.

"WebInsertion Algorithms (Rosenkrantz, Stearns, Lewis, 1974) An insertion procedure takes a sub-tour on k nodes at iteration k and determines which of the remaining n-k nodes shall be inserted to the sub-tour next (the selection step) and where (between which two nodes) it should be inserted (the insertion step). Nearest Insertion. Step 1. " - Farthest insertion algorithm python
