솔루션1) 직접 계산

class Solution:
    def addBinary(self, a: str, b: str) -> str:
        a = list(map(int, a))
        b = list(map(int, b))
        
        res = ''
        carry = 0
        while a or b or carry:
            if a:
                carry += a.pop()
            if b:
                carry += b.pop()
            
            res += str(carry % 2)
            carry = carry // 2
        return res[::-1]

솔루션2) int(), bin() 함수 사용

class Solution:
    def addBinary(self, a: str, b: str) -> str:
        return bin(int(a, base=2) + int(b, base=2))[2:]
