If we input a number formed by 4 digits and these digits are not all of the same value, then it obeys the following law. Let us process the number in the following way: 1. Arrange the digits in the way from bigger to smaller, such that it forms the biggest number that could be made from these 4 digits 2. Arrange the digits in the way from smaller to bigger, such that it forms the smallest number that could be made from these 4 digits (If there is 0 among these 4 digits, the number obtained may be less than four digits); 3. Find the difference of these two numbers that is a new four digital number Repeat the above process (1-3), we get the result 6174 or 0 Write the program to implement the above algorithm. The output from the program should show the procedure for finding this number and the number of repetitions.
