kotlin - 如何在Kotlin中定义Long Long数据类型？

Question

fun main(args: Array<String>) {
    try {
        var sum: Long = 0
        val n: Int = readLine()!!.toInt()

        for (i in 0..(n - 1)) {
            var input: Long?
            input = readLine()!!.toLong()
            sum += input
        }
        println(sum)
    } catch (ex: Exception) {
        println(ex.message)
    } 
}

我想将数据类型Long Long替换为Long。那么如何定义Long Long数据类型呢？
