Question: What is the result of an in-order traversal of the binary tree with root 1, left child 2, and right child 3?

Options:

Correct Answer: 2, 1, 3

Solution:

In-order traversal visits the left child first, then the root, and finally the right child, resulting in 2, 1, 3.

What is the result of an in-order traversal of the binary tree with root 1, left child 2, and right child 3?

What is the result of an in-order traversal of the binary tree with root 1, left child 2, and right child 3?

Step 1: Identify the root of the binary tree, which is 1.
Step 2: Identify the left child of the root, which is 2.
Step 3: Identify the right child of the root, which is 3.
Step 4: Start the in-order traversal by visiting the left child first, so we visit 2.
Step 5: After visiting the left child, visit the root, which is 1.
Step 6: Finally, visit the right child, which is 3.
Step 7: Combine the results of the visits in the order they were made: 2, 1, 3.
