Find the Lowest Common Ancestor (LCA) of two nodes in a BST

WebLCA - Lowest Common Ancestor. A tree is an undirected graph in which any two vertices are connected by exactly one simple path. In other words, any connected graph without cycles is a tree. - Wikipedia. The lowest common ancestor (LCA) is a concept in graph theory and computer science. Let T be a rooted tree with N nodes. WebIf the nodes returned to a parent from the recursive traversal is node A and node B, then the parent node is the lowest common ancestor. Example: We have to find the lowest common ancestor of node 1 and node 13. Data inside the leaf node 1 matches with the data of node 1, hence Node 1 returns node 1 to the parent node 3. pediatric hypertension table https://caprichosinfantiles.com
