This question evaluates a candidate's proficiency in object-oriented design, configuration injection, extensibility, state tracking (including ties), and testability when refactoring a Rock–Paper–Scissors tournament to support configurable rounds.

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.
