Explanation:
Inorder Traversal
- In inorder traversal, the nodes of a binary tree are visited in the order: left subtree, root, right subtree.
- This traversal starts from the leftmost node and moves towards the rightmost node.
- In each step, the left subtree is recursively visited first, then the current node is processed, and finally the right subtree is visited.
- This traversal results in visiting the nodes of the binary tree in non-decreasing order when applied to a binary search tree.
Comparison with other traversals:
- Preorder traversal visits the nodes in the order: root, left subtree, right subtree.
- Postorder traversal visits the nodes in the order: left subtree, right subtree, root.
- Level order traversal visits the nodes level by level, starting from the root and moving to the next level.
Conclusion:
- In the given scenario, where the order of visiting nodes is left subtree, root, right subtree, the correct traversal is the inorder traversal.
- Therefore, option 'B' (Inorder) is the correct answer for visiting the nodes of a binary tree in the specified order.
