🧠 Before you code — what pattern fits?
The Dota2 senate consists of Radiant (R) and Dire (D) senators voting in rounds. Each senator can ban one senator from the other party in order. Rounds repeat with the surviving senators until one party remains. All senators play optimally.
Given the string senate, predict which party announces victory: return "Radiant" or "Dire".
"RD" → "Radiant"
"RDD" → "Dire"
