2. If the sum of the digits of a number is an odd number, then multiply the sum by 3.
Step II: Now, subtract each number of step I from the number given in input such as the first number of step I from the left side is subtracted from number of the input from the left side and so on…
Step Ill: Arrange the number given in step II, in ascending order from left to right after subtracting 1 from each of the numbers.
Step IV: The sum of digits of the number in step III is written from left to right.
Step V: First arrange all the even numbers in descending order then arrange all the odd numbers in descending order.
