Symmetric Binary Tree
Each node has a left and a right subtree in a binary tree. Any binary tree, including empty, single-node trees, and subtrees, can exist. If the right subtree and the left subtree of the root node are mirror images of each other, then a binary tree is said to be symmetric.
Validate whether a binary tree is a mirror of itself if one is provided.
For illustration, the binary tree below is symmetric:
The goal is to create a recursive method called isMirror() that accepts two arguments of trees and returns true if the two trees are the mirror and false otherwise. Recursively examining two roots and subtrees beneath the root is the isMirror() method.
The following is a concise summary of the algorithmic steps:
The aforesaid algorithm is implemented in the manner shown below.
