1. Write a well-documented (commented) program, ISBN, that takes a 9-digit integer as a command-line argument, computes the checksum, and prints the ISBN number. [MO4.1] Note: You should use Javas String data type to implement it. The International Standard Book Number (ISBN) is a 10-digit code that uniquely specifies a book. The rightmost digit is a checksum digit that can be uniquely determined from the other 9 digits, from the condition that d1 + 2d2 +3d3 + ... + 10d10 must be a multiple of 11 (here di denotes the ith digit from the right). The checksum digit d1 can be any value from 0 to 10. The ISBN convention is to use the character X to denote 10. The checksum digit corresponding to 032149805 is 4 since 4 is the only value of x between 0 and 10 (both inclusive), for which 100 + 93 + 82 + 71 + 64 + 59 +48 +30 + 25 + 1x is a multiple of 11. Sample runs would be as follows.

>java ISBN 013376940

The ISBN number would be 0133769402

>java ISBN 013376947

The ISBN number would be 013376947X
