**Solution 1 Idea** : If swapping is allowed among odd numbers or even numbers, then why not construct a list of all odd numbers and even numbers and sort them in descending order. Now as we go through the input number, we check if the digit is odd, we get the best from odd, increment it. If the digit is even, we get t...
