Solutions

Solution (11-15):
Sol. In this input output question only, numbers are arranged in each step. Let us understand the logic behind it-
Logic-
Step- 1: 1st digit of all numbers will remain same and difference of 2nd and 3rd digit of all numbers use to formed new number. Ex. 135- 1 and 5-3 = 2 make new number- 12.
Step- 2: Arrange only two numbers in this step. sum of digits of the smallest number is arranged at right end and difference of digits of the largest number is arrange at left end. Rest of the numbers are placed as it is.
Again, sum of digits of the second smallest number is arranged at right end and difference of digits of the second largest number arrange at left end and so on till the 2nd last step.
Final Step – Numbers are arranged in descending order from left to right.

Input: 947 482 692 814 675 773 884 468
Step I: 93 46 67 83 62 74 84 42
Step II: 06 46 67 83 62 74 84 06
Step III: 04 06 67 83 62 74 06 10
Step IV: 05 04 06 67 74 06 10 08
Step V: 03 05 04 06 06 10 08 13
Step VI: 13 10 08 06 06 05 04 03
Step VI is the last step.
