我对这个节目很困惑。

fun main(args: Array<String>) {
    val condition1 = true
    val condition2 = false
    val condition3 = true
    val state = (if (condition1) 1 else 0) shl 2 or
            (if (condition2) 1 else 0) shl 1 or
            (if (condition3) 1 else 0)
    println(state)
    when (state) {
        0b100 -> println("Only condition1 is true.")
        0b010 -> println("Only condition2 is true.")
        0b001 -> println("Only condition3 is true.")
        0b101 -> println("condition1 and condition3 are true.")
        0b110 -> println("condition1 and condition2 are true.")
        0b011 -> println("condition2 and condition3 are true.")
        0b111 -> println("All conditions are true.")
        else -> println("All conditions are false.")
    }
}

字符串
我期望打印“condition1 and condition3 are true.”.但这段代码总是返回else块“All conditions are false.”
此外，我的IDE警告'永远无法访问'如下。

的数据
为什么会这样？有人能帮帮我吗？
