Write a program that accepts an ISBN number and displays whether it is valid or not. An ISBN (International Standard Book Number) is a ten digit code which uniquely identifies a book. The first nine digits represent Group, Publisher and Title of the book and the last digit is used as a checksum (to check whether the given ISBN is valid). Each of the digits can take any value between 0 and 9. In addition, the last digit may also take a value X (stands for 10). To verify an ISBN, calculate 10 times the first digit, plus 9 times the second digit, plus 8 times the third and so on until we add 1 time the last digit. If the number 11 can divide the sum (no remainder), the code is a valid ISBN.
