Objective:
compose a program which simulates a scissors, paper, rock double round robin tournament using a circular linked list. Players in the tournament are controlled by the computer, and they randomly choose scissors, paper or rock each round. The computer players have a win, lose, and tie record, which is displayed at the end.
Notes:
Rock wins over scissors, scissors wins over paper, and paper wins over rock.
A circular linked list is just like a single linked list (which was demonstrated in class) except the last element links to the first element.
A double round robin tournament is when each contestant competes against all other contestants in one round. In the double tournament each contestant competes against the other twice.
For instance it let’s assume there are 5 contestants named 0-4. The first round would be 0 vs 1, 0 vs 2, 0 vs 3, 0 vs 4. Then round two would be 1 vs 2, 1 vs 3, 1 vs 3, 1 vs 0. This continues until everyone competes against everyone else twice.
Suggested Methodology
You can solve this in any number of ways, and here’s a way you may take to approach this problem.
Make a generic circular linked list
Make a class player which has a name, number of wins, number of losses, and number of ties
Use the inherit properties of a circular linked list to schedule the tournament
