Answer 1

object MultiplyStrings {
  def multiplyStrings(num1: String, num2: String): String = {
    // Convert strings to integers
    val n1 = num1.toInt
    val n2 = num2.toInt

    // Perform multiplication
    val result = n1 * n2

    // Convert result back to string
    result.toString
  }

  def main(args: Array[String]): Unit = {
    val num1 = "123"
    val num2 = "456"

    println("Result: " + multiplyStrings(num1, num2))
  }
}
