Tree: Depth-First Search - Diameter of Binary Tree
Which of the following problems CANNOT be solved using the Diameter of Binary Tree pattern?
AFind the longest path between any two nodes in a binary tree
BDetermine the diameter of a binary tree
CCalculate the maximum distance between two nodes in a binary tree
DFind the maximum sum path from root to any leaf
Step-by-Step Solution
Solution:

  1. Step 1: Analyze each problem

    Options A, B, and D all relate to longest path or diameter concepts.

  2. Step 2: Identify the odd one out

    Find the maximum sum path from root to any leaf asks for maximum sum root-to-leaf path, which is a different pattern (path sum), not diameter.

  3. Final Answer:

    Option D -> Option D

  4. Quick Check:

    Maximum sum root-to-leaf ≠ diameter pattern [OK]
Quick Trick: Diameter pattern ≠ max sum root-to-leaf
Common Mistakes:
MISTAKES
  • Confusing longest path with max sum path
  • Assuming diameter solves all longest path problems
Trap Explanation:
PITFALL
  • Candidates often think diameter pattern solves all longest path problems, missing sum-based path distinctions.
Interviewer Note:
CONTEXT
  • Tests anti-pattern recognition and understanding of problem nuances
