Grokking the Coding Interview Patterns

Subtree of Another Tree

Explore how to verify whether one binary tree is a subtree of another by matching their structure and nodes. This lesson guides you through understanding the problem, constraints, and efficient implementation strategies to solve the subtree verification challenge in coding interviews.

We'll cover the following...

Statement

Given the roots of two binary trees, root and subRoot, return TRUE if there is a subtree of root with the same structure and nodes as subRoot. Otherwise, return FALSE.

A tree can only be considered a subtree of the root tree iff all the descendants (children) of the node appear in subRoot.

Constraints:

  • The number of nodes in the root tree is in the range [1,500].[1,500]. ...
