[Solved] Which of the following problems CANNOT be solved by performing a binary tree inorder traversal? - Ans: Finding the shortest path between two nodes in a binary tree | Tree: Depth-First Search

Tree: Depth-First Search - Binary Tree Inorder Traversal

Which of the following problems CANNOT be solved by performing a binary tree inorder traversal?

AFinding the sum of all nodes in a binary tree

BChecking if a binary tree is a valid binary search tree

CFinding the shortest path between two nodes in a binary tree

DReturning nodes in ascending order from a binary search tree

Step-by-Step Solution

Solution:

Step 1: Understand inorder traversal capabilities
Inorder traversal visits nodes in left-root-right order, useful for BST validation and ordered output.
Step 2: Analyze problem requirements
Finding shortest path requires graph traversal or BFS, not inorder traversal.
Final Answer:
Option C -> Option C
Quick Check:
Shortest path needs BFS/DFS, not inorder traversal [OK]

Quick Trick: Shortest path ≠ inorder traversal [OK]

Common Mistakes:

MISTAKES

Trap Explanation:

PITFALL

Candidates often think any tree problem can be solved by inorder traversal, missing pathfinding needs.
