Santa Claus is working to upgrade his list from a handwritten one to a more modern, digital solution. As youlikely already know, he must keep track of each child, their naughty/nice status, their location, position on hisroute, the toys they asked for, the elves assigned to make those toys, the elves’ working schdule, their favoritepayment methods, and keep track of their production as the year progresses, to make sure nobody will be leftout this Christmas. Keep in mind, he also needs a way to check his list twice. The following bulleted listreiterates what we’ve already discussed as requirements.• Children, their naughty/nice status (two of these for checking the list twice), location, route position (i.e.what order their presents are delivered in), requested toys.• List of elves, production assignments (which toys for which children), preferred payment methods (candy,candy-canes, candy corn, syrup), their work schdedules (assume 3, 8 hour shifts).• List of presents, whether or not…
