The topics are:Given a binary tree, find its maximum depth.The maximum depth is the number of nodes along, the longest path from the root node to the farthest leaf node.Ladder thinking: The simplest way to do this is by recursion.The code is:/** *

The topics are:Given binary trees, write a function to check if they is equal or not.The binary trees is considered equal if they is structurally identical and the nodes has the same value.problem-Solving ideas: This topic is also simple recursive
