Reading input in kotlin using generate sequence

I'm a newbie in kotlin.

I was running the below code to understand how BigDecimal works, but i'm missing something on how to safely exit from intellij terminal after entering the input. I always get NumberFormatException if i don't enter anything and press Enter key. How to quit safely and see the result. 

import java.math.BigDecimal

fun main(args: Array<String>) {
    val input = generateSequence { readLine() }
    println(input
        .map { it.toBigDecimal() }
        .fold(0.toBigDecimal()) { a, b -> a + b })
}
