(Business: check ISBN-10) An ISBN-10 (International Standard Book Number) consists of 10 digits: d1d2d3d4d5d6d7d8d9d10. The last
digit d10, is a checksum, which is calculated from the other nine digits using the following formula: (d1 * 1 + d2 * 2 + d3 * 3 + d4 * 4 + d5 * 5+ d6 * 6 + d7 * 7 + d8 * 8 + d9 * 9) % 11 If the checksum is 10, the last digit is denoted as X, according to the ISBN convention. Write a program that prompts the user to enter the first 9 digits as a string and displays the 10-digit ISBN (including leading zeros). Your program should read the input as a string. Here are sample runs: Enter the first 9 digits of an ISBN-10 as a string:013601267 The ISBN-10 number is 0136012671 Enter the first 9 digits of an ISBN-10 as a string:013031997 The ISBN-10 number is 013031997X
