1. Description

2. Solution

解析：Version 1每次投票都禁掉一个对方的参议员，由于是循环投票，因此当前投票的参议员在投票结束后进入队尾，投票直至分出胜负，即只剩下一方的参议员为止。

• Version 1

class Solution:
    def predictPartyVictory(self, senate: str) -> str:
        while 'R' in senate and 'D' in senate:
            if senate[0] == 'R':
                senate = senate[1:].replace('D', '', 1) + senate[0]
            else:
                senate = senate[1:].replace('R', '', 1) + senate[0]
        if senate[0] == 'R':
            return 'Radiant'
        else:
            return 'Dire'
