class Solution:
    def vowelStrings(self, words: List[str], left: int, right: int) -> int:
        def is_vowel(s):
            vowels = 'aeiou'
            chk1 = chk2 =0
            for vowel in vowels:
                if s.startswith(vowel):
                    chk1 = 1
                if s.endswith(vowel):
                    chk2 = 1
            return chk1 * chk2
        answer = 0
        for i in range(left, right + 1):
            answer += is_vowel(words[i])
        return answer

left 부터 right 범위 사이에 있는 word 들이 모음으로 시작해서 모음으로 끝나는지 체크하면됨
