Write a program in Kotlin
// Start of the program
fun main(args: Array<String>) {
/* The program reads an integer from the input.
* Input a single integer.
*/
val x = readLine()!!.toInt()

// Create a read-only (val) variable that equals twice of the input
// Your code here

// Print the value of the variable
// Your code here
}
// End of the program
