首先去重输入的字符串，然后转换为对应的密码表 然后遍历需要转换的字符，找到字符在非密文字符串中索引，根据索引找到对应的密码表上的值并替换，最后打印

import string


def distinct_words(words: str):
    return sorted(set(words), key=words.index)


def password_letters(words: list):
    for x in string.ascii_lowercase:
        if x not in words:
            words.append(x)
    return words


if __name__ == '__main__':
    while True:
        try:
            lower_case = string.ascii_lowercase
            pwd_list = password_letters(distinct_words(input()))
            source = [letter for letter in input()]
            for idx in range(len(source)):
                tmp = source[idx]
                if tmp in lower_case:
                    source[idx] = pwd_list[lower_case.index(tmp)]
                else:
                    source[idx] = pwd_list[lower_case.index(tmp)].upper()
            for x in source:
                print(x, end='')
            print()
        except EOFError:
            break
