Step 2: Using string interpolation, create a string literal that describes the operation we just performed. For example, given the following values for firstValue, secondValue and product respectively: 2, 4, 8. The string should read: "The product of 2 times 4 is 8". Assign this string to a constant named output.

types.swift
// Enter your code below

let firstValue = 2
let secondValue = 5

let product = firstValue * secondValue
let output: Double = product

The output constant will be a string that uses interpolation for the previously defined constants (firstValue, secondValue and product).

Here's the answer:

let firstValue = 2
let secondValue = 5
let product = firstValue * secondValue

let output = "The product of \(firstValue) times \(secondValue) is \(product)"
