Question

Using inorder traversal, in which order would the following tree be traversed?

1) Preorder
2) Inorder
3) Postorder
4) Level order

Answer 1

When using inorder traversal, a binary tree would typically be run through in a 'Left, Root, Right' sequence. This is different from Preorder ('Root, Left, Right'), Postorder ('Left, Right, Root'), and Level order ('Top to Bottom'). The answer to the question is therefore option 2) Inorder.

Step-by-step explanation:

When using inorder traversal, a tree would be traversed in a specific sequence. The sequence is as follows:

1. In ascending order of their keys, if we are talking about a binary search tree.
2. In the order of 'Left, Root, Right' for a binary tree, meaning you visit the left subtree first, then the root node, and finally the right subtree.

To clarify, if we are talking about the provided options:

• Preorder traversal visits nodes in the 'Root, Left, Right' order.
• Inorder traversal, which is the focus of your question, uses 'Left, Root, Right' order.
• Postorder traversal uses 'Left, Right, Root' order.
• Level order traversal visits nodes level by level from top to bottom.

In conclusion, the question: Using inorder traversal, in which order would the following tree be traversed? 1) Preorder 2) Inorder 3) Postorder 4) Level order is asking in which of these four methods the tree would be traversed if we use an inorder approach. The answer is option 2) Inorder.
