Question

Refactor an existing Rock–Paper–Scissors tournament with three robot players so that the number of rounds is configurable and the system also tracks ties. Describe the class/interface changes (e.g., Game, Match, Player, Strategy, Scoreboard, Config), how configuration is injected, how results are reported (per-player wins and total ties), and how you would make the design extensible for new strategies or gestures and testable.
