Web4 apr. 2024 · What is Lowest Common Ancestor in Binary Tree? The lowest common ancestor is the lowest node in the tree that has both n1 and n2 as descendants, where n1 and n2 are the nodes for which we wish to find the LCA. Hence, the LCA of a binary tree with nodes n1 and n2 is the shared ancestor of n1 and n2 that is located farthest from …
