Tree Traversal:
Tree traversal is a method of visit all the nodes of the tree and also displays their data. All the nodes are connecting via link which means edge. So the edge is used to visit all the nodes in the tree. Tree traversal is classified into three orders. They are:
- Inorder traversal
- Preorder traversal
- Postorder traversal
Inorder traversal - In this method, the left subtree is visited first after that the root node and finally right subtree. In tree traversal every node may represent a subtree itself.
Preorder traversal - In this method, the root is visited first after that the left subtree node and finally right subtree node.
Postorder traversal - In this method, the left subtree node is visited first after that the right subtree node and finally root node is visited.

- 4. Construct a binary tree whose nodes in preorder and inorder traversals are given as follows: Preorder Travesal: G, B, Q, A, C, K, F, P, D, E, R, H Inorder Travesal: Q, B, K, C, F, A, G, P, E, D, H, Rarrow_forwardc. Given 2 Arrays of Inorder and preorder traversal. Inorder sequence: {D B E A F C} Preorder sequence: {A B D E C F} Construct a tree and print the Postorder traversal.arrow_forward1. Construct a binary tree Given the order of sequence of elements below: 67, 45, 21, 88, 5, 14, 43, 20, 15, 37, 9, 40, 7, 42, 66 2. Retrieve the elements in preorder, inorder and postorder traversalsarrow_forward
- Draw a single tree whose inorder traversal is and whose postorder traversal is f, a, g, b, h, d, i, c, j, e f.g, a, h, i, d. j, e, c, barrow_forwardSuppose the nodes of a binary tree are unique and that you are given the order of elements as they are encountered in a preorder traversal and the order of the elements as they are encountered in a postorder traversal. Under what conditions can you accurately reconstruct the structure of the tree from these two traversal orders?arrow_forwardTraverse the following binary tree in (a) preorder (b) inorder and (c) postorder traversals.arrow_forward
- Assume that each node in a binary tree is distinct and that you are provided both the order in which items are discovered during a preorder traversal and a postorder traversal.

Under what conditions can the tree's structure be correctly reconstructed using these two traversal orders?arrow_forwardAssignm Exercise #4 List the nodes of the following binary tree printed in preorder, inorder, and postorder traversal orders. 11arrow_forwardAssume that each node in a binary tree is distinct and that you are provided both the order in which items are discovered during a preorder traversal and a postorder traversal. How correctly can you deduce the structure of the tree from these two traversal orders, and under what circumstances?arrow_forward
