Question
Which of the following traversal methods can be used to obtain a sorted sequence of elements in a binary search tree?
Solution
The traversal method that can be used to obtain a sorted sequence of elements in a binary search tree is the In-Order Traversal.
Here are the steps for In-Order Traversal:
- Traverse the left subtree, i.e., call In-Order Traversal on the left child.
- Visit the root.
- Traverse the right subtree, i.e., call In-Order Traversal on the right child.
In a binary search tree, In-Order Traversal retrieves data in sorted order.
