# --description--
比较并更新存储在2D阵列中的库存与新交付的第二个2D阵列。更新当前现有库存物料数量（在`arr1` ）。如果找不到商品，请将新商品和数量添加到库存数组中。返回的库存数组应按项目的字母顺序排列。如果卡住，请记得使用[Read-Search-Ask](https://forum.freecodecamp.org/t/how-to-get-help-when-you-are-stuck-coding/19514) 。尝试配对程序。编写自己的代码。
Compare and update the inventory stored in a 2D array against a second 2D array of a fresh delivery. Update the current existing inventory item quantities (in `arr1`). If an item cannot be found, add the new item and quantity into the inventory array. The returned inventory array should be in alphabetical order by item.
