Top K Brands V1 - One Brand in Go

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:

product := "Laptop"
brand := "TechPro"
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 fmt.Println(...).

Go needs strconv.Itoa(rating) to turn the int into text before joining it with +.

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

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

productLine := product
brandLine := "1. " + brand + " (" + strconv.Itoa(rating) + ")"
fmt.Println(productLine + "\n" + brandLine)
