WebRoot would be the last element in the postorder sequence, i.e., 1.Next, locate the index of the root node in the inorder sequence. Now since 1 is the root node, all nodes before 1 in the inorder sequence must be included in the left subtree of the root node, i.e., {4, 2} and all the nodes after 1 must be included in the right subtree, i.e., {7, 5, 8, 3, 6}. WebFeb 20, 2024 · For a given Binary Tree of integers, print the post-order traversal. Input Format: The first and the only line of input will contain the node data, all separated by a single space.
