class Solution:
    def get_number(self, num):
        return str(num) if num[0] == num[1] == num[2] else ""

    def largestGoodInteger(self, num: str) -> str:        
        if len(num) == 3:
            return self.get_number(num)
        res = ""
        for i in range(len(num)-2):
            n = self.get_number(num[i:i+2+1])
            if n:
                if not res:
                    res = n
                    continue
