如果使用when，如何重写else链

when (x) {
    1 -> println("x is 1")
    2 -> println("x is 2")
    else if (x > 2 && x < 5) -> println("x is between 3 and 4")
    else -> println("x is not 1, 2, or between 3 and 4")
}

when (x) {
    1 -> println("x is 1")
    2 -> println("x is 2")
    else -> when {
        x > 2 && x < 5 -> println("x is between 3 and 4")
        else -> println("x is not 1, 2, or between 3 and 4")
    }
}

when {
    x == 1 -> println("x is 1")
    x == 2 -> println("x is 2")
    x > 2 && x < 5 -> println("x is between 3 and 4")
    else -> println("x is not 1, 2, or between 3 and 4")
}
