Least common ancestor of given nodes in BST
by A Binary Search Tree is a Binary tree in which all the nodes has following properties.
- Left subtree of a node contains all the nodes having values lesser than the node.
- Right subtree of a node contains all the nodes having values higher than the node.
- Both the left and right subtree is also a Binary Search Tree.
As the name suggests, this data structure is mainly used for faster searching. In order to do that, restrictions are applied while inserting/deleting an element into the tree. As a result of these restrictions, worst case search time complexity remains at O(log n).
