At the beginning of this section, we mentioned that suspending sequences are stateless and that they reset after being used. Consider the following sequence:

val sequence = buildSequence {
    for (i in 0..9) {
        println("Yielding $i")
        yield(i)
    }
}

It's a simple sequence that can yield up to 10 values. Now, we might read the values like this:

fun main(args: Array<String>) {
    println("Requesting index 1")
    sequence.elementAt(1)

    println("Requesting index 2")
    sequence.elementAt(2)

    println("Taking 3")
    sequence.take(3).joinToString()
}

You may notice that a sequence will simply execute from the beginning for each call, which is different from using an iterator:
