// ⦁  Problem 2.Fashion Retail Management

// In the dynamic world of fashion retail, efficiently managing inventory is pivotal for catering to the ever-evolving demands of customers who seek clothing, shoes, and accessories. To meet these demands, you need to design a class named "FashionRetailInventory with updated functionality tailored to this specialized environment.
// Functionality
// Constructor
// Should have these 3 properties:
// ⦁  storehouse  (string);
// ⦁  location  (string);
// ⦁  productStock   (empty array);
// At the initialization of the FashionRetailInventory class, the constructor accepts the storehouse and location.

// addProduct (productName, size, quantity, price)
// This method adds a fashion product to the store's inventory. The method accepts four arguments:
// ⦁  productName (string);
// ⦁  size (string);
// ⦁  quantity (number);
// ⦁  price (number);
// ⦁  If a product with the same name and size already exists in the productStock, add the quantity to the product and return the following message:
// `You added ${quantity} more pieces of product ${productName} size ${size}`
// ⦁  Otherwise, add the product with properties: {productName, size, quantity, price} to the productStock and return the following message:

// `The product ${productName}, size ${size} was successfully added to the inventory`
// sendProduct (productName, size)
// This method allows the sending of a product from the store's inventory. The method accepts two arguments:
// ⦁  productName (string);
// ⦁  size (string);
// ⦁  If the product with the given name and size is not present in the productStock, throw an error with the following message:

// `The product ${productName}, size ${size} is not in the inventory`

// ⦁  Otherwise, remove the product from the productStock and return the following message:
// `The product ${productName}, size ${size} was successfully removed from the inventory`

// findProductsBySize(size)
// The method accepts one arguments:
// ⦁  size (string);

// ⦁  Iterate through the productStock array and find all products that match the specified size and return a list of the products that match the given size in the format:

// `${product1}-${quantity} pieces, ${product2}-${quantity} pieces,…`

// ⦁  If no products matching the specified size are found in the productStock, return:
// `There are no products available in that size`
// listProducts ()
// ⦁  If there are no products in stock, return:
// `${storehouse} storehouse is empty`
// ⦁  Otherwise, on the first line return:
// `${storehouse} storehouse in ${location} available products:`
// ⦁  On the next lines, display information about each product, sorted in alphabetical order by their productName in the following format:
// `${productName}/Size:${size}/Quantity:${quantity}/Price:${price}$`
