Homework 5, assigned NOV. 2 due NOV 9 at 11:59pm

### Part A

Write a program in which the main method calls a method with the heading public static int subtract(int num) that takes a three digit integer num> and does the following

• Decomposes it into three digits, digit1, digit2 and digit3.
• Using Math.max() and Math.min() determines the digits with the maximum and minimum value and assign them to maxDigit and minDigit respectively.
• Using Max3.java from OCT 31, determines the middle digit and assigns it to midDigit.
• Constructs an integer, ascend in which these digits appear in ascending order. For instance, if the original value of num was 673, the constructed integer would be 367.
• Repeats the last step but this time produces the digits in descending order. So in our example, it would produce 763. It assigns this to descend.
• Prints these two values.
• Subtracts these two numbers (descend - ascend) and returns this value in the method.

### Part B

• Write another program that calls method subtract until the the method returns a value that doesn't change, i.e., 495.
