def str_dif(s1, s2):
    if len(s1) != len(s2):
        return
    res = ''
    for i in range(len(s1)):
        if s1[i] == s2[i]:
            res += s1[i]
        else:
            res += '0'
    return res


def main():
    line = input()
    s1, s2 = line.split()
    res = str_dif(s1, s2)
    print(res)
