Answer 1

fun 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
    return result.toString()
}

fun main() {
    val num1 = "123"
    val num2 = "456"

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