Can I understand more why it is sufficient to check the occurences of each character to keep the score, and we do not need the generate the words to check for occurrences?

def minion_game(string): vowels = ('A', 'E', 'I', 'O', 'U') kevin_score = 0 stuart_score = 0 len_str = len(string)

for i in range(len_str):
    if string[i] in vowels:
        kevin_score += (len_str - i)
    else:
        stuart_score += (len_str - i)

if kevin_score > stuart_score:
    print(f'Kevin {kevin_score}')
elif stuart_score > kevin_score:
    print(f'Stuart {stuart_score}')
else:
    print('Draw')

if name == 'main': s = input() minion_game(s)

def minion_game(string): n = len(string) S = string.upper() # be robust to case vowels = set("AEIOU")

kevin = 0   # vowel player
stuart = 0  # consonant player

for i, ch in enumerate(S):
    if ch in vowels:
        kevin += n - i
    else:
        stuart += n - i

if kevin > stuart:
    print(f"Kevin {kevin}")
elif stuart > kevin:
    print(f"Stuart {stuart}")
else:
    print("Draw")

who's code passed test case 4?
