Tree: Depth-First Search - Binary Tree Inorder Traversal
Which traversal method visits nodes in the order: left child, current node, then right child, producing a sorted sequence for a binary search tree?
Which traversal method visits nodes in the order: left child, current node, then right child, producing a sorted sequence for a binary search tree?
easy💻 Programming Q1 of Q15
Step-by-Step Solution
Solution:
Step 1: Understand traversal orders
Preorder visits node before children, postorder after children, level-order by levels.Step 2: Identify inorder traversal
Inorder visits left subtree, then node, then right subtree, which yields sorted order in BST.Final Answer:
Option D -> Option DQuick Check:
Left, node, right order matches inorder [OK]
Quick Trick: Left-node-right order is inorder traversal [OK]
Common Mistakes:
MISTAKES- Confusing preorder with inorder
- Thinking postorder is left-node-right
- Assuming level-order is inorder
Trap Explanation:
PITFALL- Preorder and postorder are common confusions but differ in node visit order.
Interviewer Note:
CONTEXT- Tests understanding of basic binary tree traversal orders and their properties.
