Question
Which type of traversal of binary search tree outputs the value in sorted order ?a) Pre-orderb) In-orderc) Post-orderd) None
Solution
The type of traversal of a binary search tree that outputs the value in sorted order is b) In-order.
Here's why:
-
In a binary search tree, the left child node is always less than the parent node, and the right child node is always greater than the parent node.
-
In an in-order traversal, the process is: traverse the left subtree, visit the root node, then traverse the right subtree.
-
Therefore, in an in-order traversal, you would first visit the left child node (the smallest element), then the parent node, and finally the right child node (the largest element).
-
This means that an in-order traversal of a binary search tree always gives you the nodes in ascending (sorted) order.

Say that we have a binary search tree with the keys 1, 2, 3, 4, 5, 6, 7. A preorder traversal of the tree prints the keys in the sequence 4, 1, 3, 2, 6, 5, 7. What sequence would be printed by a postorder traversal of the tree?
