Top K Brands V2 - Better of Two in Scala

Practice

Two brands sell the same product. Show the one with the higher rating.

You start with:

        val brand1 = "TechPro"
        val rating1 = 4
        val brand2 = "MegaCorp"
        val rating2 = 5

        var bestBrand: String = ""
        var bestRating: Int = 0

Build:

1. MegaCorp (5)

Rules:

Use if/else to pick the winner: brand1 when rating1 > rating2, otherwise brand2.
The starter already declares bestBrand and bestRating: assign the winner's name and rating to them inside the branches.
Format the result as "1. Brand (rating)" and print it with println(...).

Pick the winner into bestBrand and bestRating first, then build the output text from them.

Scala's + on a String and an Int converts the number to text for you.

        val brand1 = "TechPro"
        val rating1 = 4
        val brand2 = "MegaCorp"
        val rating2 = 5

        var bestBrand: String = ""
        var bestRating: Int = 0
        if (rating1 > rating2) {
            bestBrand = brand1
            bestRating = rating1
        } else {
            bestBrand = brand2
            bestRating = rating2
        }
        println("1. " + bestBrand + " (" + bestRating + ")")
