Step 1 : First We Compare 17 to 45 and 56 if it is greatest then we can say that 17 is greatest else we go to next step

Step 2: Then we compare 45 to 56 and 17 if it is greatest then we can say that 45 is greatest else we go to next step
Step 3: Then we compare 56 to 45 and 17 if it is greatest then we can say that 56 is greatest else we go to next step (Special Case)

Step 4: This is the last case if all numbers are same or equal then it will print a message that
