Write Pseudocode:

For each of the following problems provide:

1. inputs
2. outputs
3. error conditions
4. an algorithm using the pseudocode reference used in class
5. a set of test cases
6. the minimum number of operations executed in your algorithm
7. the maximum number of operations executed in your algorithm

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 0 and 10 for which10*0 + 9*2 + 8*0 + 7*1 + 6*3 + 5*1 + 4*4 + 3*5 + 2*2 + 1*x is a multiple of 11.
• Write an algorithm that reads an integer number of 9 digits and displays the ISBN the checksum digit.
• 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 composed of 9 positive integer digits between 0-9. Also assume that the input is a valid ISBN number without the checksum digit.
