    Grocery Store Helper!

    You are tasked with writing a program that finds the areas/aisles of the grocery store where a user will find the items in their grocery list. 

    In the method below named "GetStoreAreasForGroceryList", add your code to return the areas of the store for a provided grocery list.

    * Assume all product names in the grocery list are an exact match with the store's products.

    * Preserve the original order of the areas/aisles as they appear in the GroceryProduct dataset. 

    * Please only include unique store area names once in the output. 

    * Googling for syntax is allowed, but you cannot google for the answer. 

    * No AI tools are allowed to be used during this exercise.
