Leetcode Solutions

Depth First Search

  1. Define a helper function isIdentical that takes two nodes from two trees and recursively checks if they are identical.
  2. Define the main function isSubtree that uses DFS to traverse the root tree.
  3. For each node in the root tree, use isIdentical to check if the subtree rooted at that node is identical to subRoot.
  4. If isIdentical returns true for any node, return true for the isSubtree function.
  5. If no such node is found after the traversal, return false.
