Lca of nodes
WebInput: root = [0,1,3,null,2] Output: [2] Explanation: The deepest leaf node in the tree is 2, the lca of one node is itself. Constraints: The number of nodes in the tree will be in the range [1, 1000]. 0 <= Node.val <= 1000 The values of the nodes in the tree are unique. WebAs you can see here, LCA is nothing but lowest common parent of two nodes. Recursive Algorithm (For nodes A and B): If node is null, return it If we find A or B, return it. Traverse left subtree and right subtree If we get both left and right for any node as not null, it will be lowest common ancestor of two given nodes 1 2 3 4 5 6 7 8 9 10 11 12
