Tree: Depth-First Search - Binary Tree Inorder TraversalWhich of the following problems CANNOT be solved by performing a binary tree inorder traversal?AFinding the sum of all nodes in a binary treeBChecking if a binary tree is a valid binary search treeCFinding the shortest path between two nodes in a binary treeDReturning nodes in ascending order from a binary search treeCheck Answer
Step-by-Step SolutionSolution:Step 1: Understand inorder traversal capabilitiesInorder traversal visits nodes in left-root-right order, useful for BST validation and ordered output.Step 2: Analyze problem requirementsFinding shortest path requires graph traversal or BFS, not inorder traversal.Final Answer:Option C -> Option CQuick Check:Shortest path needs BFS/DFS, not inorder traversal [OK]Quick Trick: Shortest path ≠ inorder traversal [OK]Common Mistakes:MISTAKESAssuming inorder traversal can find shortest pathsConfusing traversal with pathfindingTrap Explanation:PITFALLCandidates often think any tree problem can be solved by inorder traversal, missing pathfinding needs.Interviewer Note:CONTEXTTests ability to distinguish traversal from pathfinding problems
