Tree: Depth-First Search - Symmetric Tree (DFS Approach)

Which of the following problems CANNOT be solved using the Symmetric Tree (DFS) approach?

ADetermine if a binary tree is height-balanced.

BCheck if a binary tree is a mirror of itself.

CCheck if a binary tree is symmetric around its center.

DVerify if two binary trees are mirror images of each other.

Step-by-Step Solution

Solution:

Step 1: Analyze problem statements
Options A, B, and D all relate to symmetry or mirror checks, which fit the symmetric tree pattern.
Step 2: Identify the odd one out
Determining if a binary tree is height-balanced is unrelated to symmetry and requires different algorithms.
Final Answer:
Option A -> Option A
Quick Check:
Height-balanced check is a different pattern [OK]

Quick Trick: Height-balanced ≠ symmetric tree problem [OK]

Common Mistakes:

MISTAKES

Trap Explanation:

PITFALL

Candidates often think all tree property checks can be solved with symmetry DFS, but height-balance is distinct.
