/题目描述
密码是我们生活中非常重要的东东，我们的那么一点不能说的秘密就全靠它了。哇哈哈. 接下来渊子要在密码之上再加一套密码，虽然简单但也安全。
假设渊子原来一个BBS上的密码为zvbo9441987,为了方便记忆，他通过一种算法把这个密码变换成YUANzhi1987，这个密码是他的名字和出生年份，
怎么忘都忘不了，而且可以明目张胆地放在显眼的地方而不被别人知道真正的密码。他是这么变换的，大家都知道手机上的字母：
1--1， abc--2, def--3, ghi--4, jkl--5, mno--6, pqrs--7, tuv--8 wxyz--9, 0--0,
就这么简单，渊子把密码中出现的小写字母都变成对应的数字，数字和其他的符号都不做变换，
声明：密码中没有空格，而密码中出现的大写字母则变成小写之后往后移一位，
如：X，先变成小写，再往后移一位，不就是y了嘛，简单吧。记住，z往后移是a哦。
输入描述:
输入包括多个测试数据。输入是一个明文，密码长度不超过100个字符，输入直到文件结尾
输出描述:
输出渊子真正的密文
