Python - Binary Search Tree: Remove Node Implementation

WebA binary search tree (BST) is a data structure in which each node has at most two child nodes, left and right. The left child node holds a value less than or equal to its parent node, and the right child node holds a value greater than the parent node.

WebSince this is a binary search tree, we are guaranteed that each node will have at most two children.

The complexity of the deletion procedure is O(h). Tree Sort. One interesting application of binary search tree is in the tree sort. The in-order traversal of BST results into the sorted order of the keys. This is known as the tree sort and the complexity of this sort is O(nh).
