// Enter your code below extension Calculator { func square(_ value: Double) -> Double { return value.squareRoot() } }
protocol Calculator {
func square(_ value: Double) -> Double

// Enter your code below
extension Calculator {
func square(_ value: Double) -> Double {

}

extension Calculator {
func square(_ value: Double) -> Double {
return (value * value)
}
}
