As you should recal in this class, there were several phases of groups throughout the semester. At times, two people in the class would end up in a group with a person who was in their group in the previous phase! In this problem, you should implement a function that could be used to help check that that doesn't happen. Write a program namesfind valid groups. This is a function that should take three parameter variables. The first parameter is...
