We have a fun little task for your Friday lunch hour:
Given an array of integers, rearrange the integers so no two consecutive integers have a sum that is divisible by 3, or indicate that such an arrangement is not possible.
Your task is to write a program to rearrange an array of integers as described above. When you are finished, you are welcome to read or run a suggested solution, or to post your own solution or discuss the exercise in the comments below.
