题目描述
Igor K. always used to trust his favorite Kashpirovsky Antivirus. That is why he didn't hesitate to download the link one of his groupmates sent him via QIP Infinium. The link was said to contain "some real funny stuff about swine influenza". The antivirus had no objections and Igor K. run the flash application he had downloaded. Immediately his QIP Infinium said: "invalid login/password".
Igor K. entered the ISQ from his additional account and looked at the info of his main one. His name and surname changed to "H1N1" and "Infected" correspondingly, and the "Additional Information" field contained a strange-looking binary code 80 characters in length, consisting of zeroes and ones. "I've been hacked" — thought Igor K. and run the Internet Exploiter browser to quickly type his favourite search engine's address.
Soon he learned that it really was a virus that changed ISQ users' passwords. Fortunately, he soon found out that the binary code was actually the encrypted password where each group of 10 characters stood for one decimal digit. Accordingly, the original password consisted of 8 decimal digits.
Help Igor K. restore his ISQ account by the encrypted password and encryption specification.
伊戈尔·K. 一直非常信赖他最喜爱的卡什皮罗夫斯基杀毒软件。因此,当他的一个小组同学通过 QIP Infinium 给他发送了一个链接,并称其中包含“一些关于猪流感的真正搞笑内容”时,他毫不犹豫地下载了该链接。杀毒软件未提出任何警告,于是伊戈尔·K. 运行了他所下载的 Flash 应用程序。随即,他的 QIP Infinium 客户端显示:“登录名/密码无效”。
伊戈尔·K. 使用他的备用账户登录 ISQ 系统,查看其主账户的信息。他发现自己的姓名与姓氏分别被更改为“H1N1”和“Infected”,而“附加信息”字段中则包含一段长度为 80 位、由 0 和 1 组成的、外观奇特的二进制码。“我被黑了”——伊戈尔·K. 暗想,随即打开 Internet Exploiter 浏览器,迅速输入他最常使用的搜索引擎网址。
很快他了解到,这的确是一种病毒,专门篡改 ISQ 用户的密码。幸运的是,他很快发现这段二进制码实际上就是加密后的密码,其中每 10 位二进制字符对应一位十进制数字。因此,原始密码由 8 位十进制数字组成。
请根据加密后的密码及加密规则,帮助伊戈尔·K. 恢复他的 ISQ 账户。
