Problem 1: Check ISBN-10 Number 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-10 convention. Write a Java program that prompts the user to enter the first 9 digits and displays the 10-digit ISBN (including leading zeros). You have to solve this problem using loops. Sample Input/Output Enter the first 9 digits of an ISBN: 013601267 The ISBN-10 number is 0136012671 Enter the first 9 digits of an ISBN: 013031997 The ISBN-10 number is 013031997X Enter the first 9 digits of an ISBN: 0135042 You need to enter exactly 9 digits
