Kotlin 区间问题

//区间
    val a到z = "a".."z"
    val d在其中 = "d" in a到z
    val 一到一百 = 1..100
    val 三十八在其中 = 38 in 一到一百
    val 倒计时 = 10 downTo (0)
    val 一百到二百 = 100.rangeTo(200)
    val 一百到一百间的奇数 = 一到一百.step(2)
    println(a到z)
    println(d在其中)
    println(一到一百)
    println(三十八在其中)
    println(倒计时)
    println(一百到二百)
    println(一百到一百间的奇数)
    for (i in 一百到一百间的奇数){
        print(i)
        if (i==99)
            break
            print(",")

    }
    println()
    val 倒数的奇数 = (1..100).step(2).reversed()
    for (i in 倒数的奇数){
        print(i)
        if (i == 1) break
        print(",")
    }
