1. Give a recursive algorithm in pseudocode to compute the diameter of a binary tree.

First code is top, second code is on bottom. This is for Java. What makes these two codes different? (a) If x = 3, what will the first (code) print out? (b) If x = 3, what will the second (code) print out? (c)If x = 1, what will the first (code) print out? (d) If x = 1, what will the second (code) print out?

This assignment will help you to get started with NetBeans and using Java compiler:   To begin, put a block comment at the beginning of your Java file (and every Java source file in the future) with the assignment number, assignment title, program author [your name], and the date it's due. Next, similar to the programs presented in the first chapter of the textbook, use System.out object to display the following information: Your first name The name of the operating system you are using The name of your project (or simply the folder name if not using the IDE) The name of the class that contains the main() method in your source file. Note: Your program should print each of the above items on a separate output line. "The name of the class that contains the main() method in your source file.public class MyClass {    public static void main(String[]) {        System.out.println( "Hi" );    }}

Do not attempt, if you are using other's work. I'll give multiple dislikes for plagiarism and also will report your account. Give unique answer others are wrong. Question: Write a Java program that takes user input for two numbers, multiplies them, and prints the result. Ensure that your program is user-friendly, handling different data types, and providing meaningful output. Submission Guidelines: Use appropriate variable types for user input and the result. Implement input validation to handle unexpected user inputs. Print a clear and informative message along with the result.
