Description

Every officially published book has an ISBN number corresponding to it. The ISBN code consists of a 9 digit number, a 1 digit identifier, and a 3 digit delimiter. Its specified format is $x-xxx-xxxxx-x$, where the symbol - is the delimiter (a minus sign on the keyboard) and the last digit is the identifier. For example, $0-670-82162-4$is a standard ISBN code. The first digit of the ISBN code indicates the publishing language of the book, for example, $0$represents English; The three digits after the first delimiter $-$represent the publishing house, for example, $670$represents Viking Publishing House; The five digits after the second delimiter represent the number of the book published by the publisher; The last digit is the identification code.

The calculation method of the identification code is as follows:

Multiply the first digit by $1$and the last digit by $2...$, and so on. Use the result $mod11$to obtain the remainder, which is the identification code. If the remainder is $10$, the identification code is the uppercase letter $X$. For example, the identification code $4$in the $ISBN$number $0-670-82162-4$is obtained as follows: multiply the $9$digits $067082162$from left to right by $1, $2,..., $9$, and then add them up, which is $0 × 1+6 × 2+...+2 × 9=158$. Then take the result $4$of $158mod11$as the identification code.

Your task is to write a program to determine if the identification code in the $ISBN$number input is correct. If it is correct, only $Right$will be output; If there is an error, output the $ISBN$number that you believe is correct.
