Can anybody help me to write pseudocode for this problem?

2.ISBN. 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 in the following manner: Multiply the first digit by 10, the second by 9, the third by 8, and so on, down to the ninth digit by 2. . Add the values together. Divide the sum by 11. What is the remainder? If the remainder is 0, the checksum is 0; otherwise, subtract the remainder from 11 to get the checksum digit. If the checksum that you come up with is 10, then X is used as the checksum digit! As an example, the checksum digit corresponding to 020131452 is 5 since 5 is the only value of x between O and 10 for which 10*0+992 +840 + 7*1 + 6*3 + 5*1 + 4*4 + 35 + 2*2 + 1*x is a multiple of 11. Write an algorithm that reads an integer number of 9 digits and displays the checksum digit of the ISBN Hint 1: to extract the rightmost digit of a number use: COMPUTE digit AS number MODULUS 10 Hint 2: to remove the rightmost digit of a number use: COMPUTE number AS number / 10 Hint 3: for full credit use a loop to compute the sum Assume the input value is a 9-digit positive integer. Also assume that the input is a valid ISBN number without the checksum digit
