Which traversal technique visits the left subtree, then the root, and ...
Traversal Technique: Inorder
In the Inorder traversal technique of a binary tree, the nodes are visited in the following order:
- Visit the left subtree
- Visit the root
- Visit the right subtree
Explanation:
1. Visit the left subtree: In Inorder traversal, we first recursively visit the left subtree of the current node. This means we move to the left child of the current node until we reach a node with no left child.
2. Visit the root: After visiting the entire left subtree, we visit the root node of the current subtree. This is the node from which we started the traversal.
3. Visit the right subtree: Finally, we recursively visit the right subtree of the current node. This involves moving to the right child of the current node and following the same process as we did for the left subtree.
Example:
Consider a binary tree with the following structure:
1
/ \
2 3
/ \
4 5
In Inorder traversal, the nodes will be visited in the order: 4, 2, 5, 1, 3. This follows the left-root-right sequence, as mentioned above.
Therefore, based on the characteristics of Inorder traversal, it is the traversal technique that visits the left subtree, then the root, and finally the right subtree of a binary tree.
