//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(",")
        }
