Title: 判断字符串的两半是否相似

class Solution:
    def halvesAreAlike(self, s: str) -> bool:
        yuan = ['a', 'e', 'i', 'o', 'u', 'A', 'E', 'I', 'O', 'U']
        n = len(s)
        a = s[:n // 2] # 前半段
        b = s[n // 2:] # 后半段
        cnt_a, cnt_b = 0, 0
        for ch in a:
            if ch in yuan:
                cnt_a += 1 # a中元音个数
        for ch in b:
            if ch in yuan:
                cnt_b += 1 # b中元音个数
        if cnt_a == cnt_b:
            return True
        return False
