Practice Flip Equivalent Binary Trees
Read the task, work through the examples, and check your approach against the constraints. Use the original LeetCode task for coding and submissions.
Problem Statement
For a binary tree T, we can define a flip operation as follows: choose any node, and swap the left and right child subtrees. A binary tree X is flip equivalent to a binary tree Y if and only if we can make X equal to Y after some number of flip operations. Given the roots of two binary trees root1 and root2, return true if the two trees are flip equivalent or false otherwise.

true
# Example 2
root1 = [], root2 = []
true
# Example 3
root1 = [], root2 = [1]
