- Answer the following problem inline in your application. Applications that don’t have this will be ignored.
Problem 1: Write best practice code in ruby to calculate the check digit of an ISBN13 barcode
The algorithm is:
Take each digit, from left to right and multiply them alternatively by 1 and 3
Sum those numbers
Take mod 10 of the summed figure
Subtract 10 and if the end number is 10, make it 0
Example for 978014300723:
(9×1) + (7×3) + (8×1) + (0×3) + (1×1) + (4×3) + (3×1) + (0×3) + (0×1) + (7×3) + (2×1) + (3×3)
86 mod 10 = 6
10 – 6 = 4
Therefore the complete ISBN is: 9780143007234
Problem 2: Do a code review of the following code
class AddressesController < ApplicationController
# other code was here
if @address.account_id!=@auth_account.id && !@auth_account.admin_at(@site) && !@auth_account.manager_at(@site) && !@auth_account.staff_at(@site)
flash[:error]=”You dont have permission to access this page”
flash[:success]=”Address deleted successfully”
