Solution in Kotlin (1.3.71) (judge verdict: Runtime Error)

package abc162

/** A - Lucky 7 */
import java.util.*

fun main(args: Array<String>) {
    val sc = Scanner(System.`in`)

    // 3桁整数の入力
    val inputInt = sc.nextInt()
    val inputList = inputInt.toString().split("")

    var flg = false
    inputList.forEach {
        if (it == "7") {
            flg = true
            return@forEach
        }
    }

    if (flg) {
        println("Yes")
    } else {
        println("No")
