WebFind the lowest common ancestor(LCA) of the two nodes. The lowest common ancestor is the node with largest depth which is the ancestor of both nodes. The node has an extra attributeparentwhich point to the father of itself. The root's parent is null. Example. For the following binary tree: 4 / \ 3 7 / \ 5 6 LCA(3, 5) =4. LCA(5, 6) =7. LCA(6, 7) =7
