In a binary tree class, implement a Python method equal, that takes in another binary tree (other) as a parameter and returns true if both binary trees are equal, otherwise, the function returns False. What is the time complexity of your function? class BinaryTree:     class _Node:         def __init__(self, element, left = None, right = None):             self._left = left             self._right = right             self._element: int = element     def __init__(self):         self._root = None         self._size = 0

In Java,  Complete the incomplete method of ExpressionTree.java. The incomplete methods are private Node parsePrefix(Scanner input) // Required public void parseInfix(String string) // Optional public void parsePostfix(String string) // Optional Implementations of parseInfix and parsePostfix require use of a stack. Implementation of parsePrefix does not. Read all of the ExpressionTree.java file before starting your implementation, so that you see the helper methods that are provided and get an idea of the context for your implementation.  Although not needed for your implementation, you should be sure you understand how the toStringPrefix, toStringInfix, and toStringPostfix methods work. Note: The main() method accepts a single String as its argument. The String should be a prefix, infix, or postfix mathematical expression with no characters other than operators (+, -, *, and /) and operands (single characters a-z).  As written, the main() method calls parsePrefix() to create an…
