要理解优化的作用，缩进是否减少了判断？

2410. 运动员和训练师的最大匹配数
class Solution:
    def matchPlayersAndTrainers(self, players: List[int], trainers: List[int]) -> int:
        players.sort(reverse=True)
        trainers.sort(reverse=True)
        k=len(trainers)
        i=ans=0
        for v in players:
            if v <=trainers[i]:
                ans+=1 
                i+=1
            if i==k:
                return k
        return ans 
#下面的if 又缩进了
class Solution:
    def matchPlayersAndTrainers(self, players: List[int], trainers: List[int]) -> int:
        players.sort(reverse=True)
        trainers.sort(reverse=True)
        k=len(trainers)
        i=ans=0
        for v in players:
            if v <=trainers[i]:
                ans+=1 
                i+=1
                if i==k:
                    return k
        return ans
