题目：小黄人游戏--The Minion Game
题目要求：
对于输入的字符串，计算所有可能的子字符串中，以辅音字母开头的给Stuart加分，元音字母开头的给Kevin加分。然后比较两者的总分，输出胜者或者平局
解题代码：
def minion_game(string):
vowels = {'A', 'E', 'I', 'O', 'U'}
stuart_score = 0
kevin_score = 0
n = len(string)
for i in range(n):
char = string[i]
if char.upper() in vowels:
kevin_score += (n - i)
else:
stuart_score += (n - i)
if stuart_score > kevin_score:
print(f'Stuart {stuart_score}')
elif kevin_score > stuart_score:
print(f'Kevin {kevin_score}')
else:
print('Draw')
if __name__ == '__main__':
s = input().strip()
minion_game(s)
