WebExplanation: The LCA of nodes 2 and 4 is 2, since a node can be a descendant of itself according to the LCA definition. Example 3: Input: root = [2,1], p = 2, q = 1 Output: 2 Constraints: * The number of nodes in the tree is in the range [2, 105]. * -109 <= Node.val <= 109 * All Node.val are unique. * p != q * p and q will exist in the BST. WebNow node 7’s parent and ancestor are updated, it is merged into node 3 as well, so the size of node 3 disjoint set is now 2. At this point we are done processing node 7, so we mark it as visited (colored black). Node 8 is processed next, after creating SetNode for it, we can start printing the LCA’s for node pairs with node 8, in the ... WebNormal LCA: - case 1: if root is null, return null - case 2: if root is one of the nodes, return root - case 3: if root's left and right both return a node (means both node found), root is the lca - case 4: if only one of the child return a node, keep passing that node back up 2. If result of normal lca is one of the two nodes: density of steel in metric units

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

WebHere in this program we have written a function to find out the lowest common ancestor of two nodes in a given tree. 2. Function lca (root,node_1,node_2) takes in three parameters which are root node of the tree, node_1 and node_2 are the two nodes whose LCA is to be determined. Function LCA returns a node therefore it is of (struct node *) type.

WebYour task is to complete the function LCA () which takes the root Node of the BST and two integer values n1 and n2 as inputs and returns the Lowest Common Ancestor of the Nodes with values n1 and n2 in the given BST.
