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 have a system in place that updates our inventory for us. It +*& was developed by a no-nonsense type named Leeroy, who has moved on to +*& new adventures. Your task is to add the new feature to our system so that +*& we can begin selling a new category of items. +*& +*& First an introduction to our system: +*& +*& - All items have a Sell In value which denotes the number of +*& days we have to sell the item +*& - All items have a Quality value which denotes how valuable the item is +*& - At the end of each day our system lowers both values for every item +*& +*& Seems pretty simple, right? Well this is where it gets interesting: +*& +*& - Once the sell by date has passed, Quality degrades twice as fast +*& - The Quality of an item is never negative +*& - "Aged Brie" actually increases in Quality the older it gets +*& - The Quality of an item is never more than 50 +*& - "Sulfuras", being a legendary item, never has to be sold or +*& decreases in Quality +*& - "Backstage passes", like aged brie, increases in Quality as its +*& Sell In value approaches; Quality increases by 2 when there +*& are 10 days or less and by 3 when there are 5 days or less +*& but Quality drops to 0 after the concert +*& +*& We have recently signed a supplier of conjured items. This requires an +*& update to our system: +*& +*& - "Conjured" items degrade in Quality twice as fast as normal items +*& +*& Feel free to make any changes to the Update Quality method and add any new +*& code as long as everything still works correctly. However, do not alter +*& the Item class directly or Items table attribute as those belong to the +*& goblin in the corner who will insta-rage and one-shot you as he doesn't +*& believe in shared code ownership (you can make the Update Quality method +*& and Items property static if you must, we'll cover for you). +*& +*& Just for clarification, an item can never have its Quality increase +*& above 50, however "Sulfuras" is a legendary item and as such its Quality +*& is 80 and it never alters. + +PROGRAM yy_pao_gilded_rose. + + +*& Production Code -
