WebThe root will be the first element in the preorder sequence, i.e., 1.Next, locate the index of the root node in the inorder sequence. Since 1 is the root node, all nodes before 1 in the inorder sequence must be included in the left subtree, i.e., {4, 2} and all the nodes after 1 must be included in the right subtree, i.e., {7, 5, 8, 3, 6}.Now the problem is reduced to … WebMar 16, 2024 · On the other hand, postorder traversal visits the nodes in the order left child, right child, and parent. Knowing this, we can say that the last element in the postorder array is the root node, and its index in the inorder array divides the tree into left and right subtrees. We can recursively apply this logic to construct the entire binary tree.

WebConstruction of the binary tree from Inorder and Postorder Traversal Example: Inorder Traversal: [4, 2, 5, 1, 3] Postorder Traversal: [4, 5, 2, 3, 1] Now from the postorder traversal we can see the right most element, node 1 is the root node. From Inorder traversal we can see that node 3 is on right of root node 1, and others on left. WebJan 25, 2024 · Inorder traversal is a special traversal that helps us to identify a node and its left and right subtree. Postorder traversal always gives us the root node as its last element. Using these properties we can construct the unique binary tree. Given this example: Here 10 (last element of postorder) is the root element.
