Compare and contrast (ie explain the similarities and differences) in your own words sentinel-controlled loops with loops controlled by an accumulator. Illustrate your answer using the following example program fragments.  You may assume inputInt is a method that inputs an integer from the user. Note you are NOT being asked to explain the code below itself but to use it to help explain any points you make that compare and contrast the concepts.

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.

Write a recursive algorithm with the following prototype: int add (int x, int y); that returns x if y is 0; and adds x to y otherwise. THE FUNCTION MUST BE RECURSIVE. (hint: the base case should involve a test for y being 0; recursive case should reduce y towards 0)
