【leetcode系列】小菜鸡的leetcode第5题:有效括号

一个很妙的解法：
class Solution:
    def isValid(self, s: str) -> bool:
        while '{}' in s or '[]' in s or '()' in s:
            s = s.replace('{}','')
            s = s.replace('[]','')
            s = s.replace('()', '')
        return s == ''

if __name__ == '__main__':
    s = "(]"
    a=Solution()
    print(a.isValid(s))
