Top K Brands V1 - One Brand in Swift

Practice

E-commerce search page: when a shopper searches a product, show the top-rated brand selling it. In v1 there's just one product and one brand.

You start with:

        let product = "Laptop"
        let brand = "TechPro"
        let rating = 4

Build:

Laptop
1. TechPro (4)

Rules:

The first line is the product name.
The second line is a ranked entry written as "1. Brand (rating)".
Keep each line in its own variable (productLine and brandLine), join them with a newline "\n" and print the result with print(...).

Swift puts any value into a string with interpolation: "\(rating)".

productLine + "\n" + brandLine joins both lines into one string.

        let product = "Laptop"
        let brand = "TechPro"
        let rating = 4

        let productLine = product
        let brandLine = "1. \(brand) (\(rating))"
        print(productLine + "\n" + brandLine)
