Hi and welcome to the Inn. As you know, we are a small inn with a prime location in a prominent city ran by a friendly innkeeper named Allison. We also buy and sell only the finest goods. Unfortunately, our goods are constantly degrading in quality as they approach their sell by date. We need a system to help us keep track of the value of the items in our shop. ## Introduction to the shop The shop tracks items in its inventory by their quality and the number of days remaining until the item needs to be sold. ### Item Properties | Property | Description | | --------- | ----------------------------------------| | `sellIn` | number of days we have to sell the item | | `quality` | how valuable the item is | - At the end of each day, `quality` decrements by `1` - At the end of each day, `sellIn` decrements by `1` - Once the sell by date has passed, `quality` degrades twice as fast - The `quality` of an item is never negative - The `quality` of an item is never more than `50` #### Special Items Some types of items in our shop deviate from the normal deprecation rules: | Item | Property | | ------------------------ | -------------------------------------------------------- | | Aged Brie | Quality increments by `1` as the sell by date approaches | | Sulfuras | Never has to be sold and never decreases in quality | | Concert backstage passes | `quality` increments by `1` as the sell by date approaches and increments by `2` when there are 10 days or less; the `quality` drops to 0 after the sell by date | ## Requirements - You must create an inventory system that, given a list of items in the shop, calculates the value of the items `n` days in the future. - The system should be unit tested to ensure the values being reported are correct. - Preferably the system should be written using Java 8. The items currently in our inventory are: | Item | `sellIn` | `quality` | | ----------------------------------------- | -------- | --------- | | +5 Dexterity Vest | 10 | 20 | | Aged Brie | 2 | 0 | | Elixir of the Mongoose | 5 | 7 | | Sulfuras | 0 | 80 | | Concert backstage passes | 15 | 20 | ### Optional - Create the system as a SpringBoot REST service - Package the application in a Docker container for deployment to a cloud service.
