P1055 [noip2008 popularization group] ISBN number

Title Description

Every book officially published has a ISBN The number corresponds to ,ISBN Code includes 99 Digit number 、11 Bit ID and 33 Bit separator , The format is as follows x-xxx-xxxxx-x, Symbols - It's the separator （ The minus sign on the keyboard ）, The last one is the identification number , for example 0-670-82162-4 It's a standard ISBN code .ISBN The first digit of the code indicates the language of publication of the book , for example 00 For English ; First separator - The next three figures represent the publisher , for example 670670 On behalf of Viking press ; The five digits after the second separator represent the number of the book in the publishing house ; The last digit is the identification number .

The identification code is calculated as follows ：

Multiply the first number by 11 Multiply the last digit by 22…… And so on , Use the results \bmod 11mod11, The remainder obtained is the identification code , If the remainder is 1010, The identification code is capital letters XX. for example ISBN number 0-670-82162-4 Identification code in 44 This is how I got ： Yes 067082162 this 99 A digital , From left to right , Times, respectively, 1,2,...,91,2,...,9 And then sum up , namely 0×1+6×2+……+2×9=1580×1+6×2+……+2×9=158, And then take 158 \bmod 11158mod11 Result 44 As an identification number .

Your task is to write a program to judge the input ISBN Is the identification number correct , If correct , Only output Right; If the error , Then output what you think is correct ISBN number .

Input format

A character sequence , For a book ISBN number （ Make sure the input matches ISBN Format requirements for number ）.

Output format

a line , If you type ISBN The ID of the number is correct , Then output Right, otherwise , In the prescribed form , Output correct ISBN number （ Include separator -）.
