kotlin for loop

for (i in 1..5) print(i)
-> 12345

for (i in 5 downTo 1) print(i)
-> 54321

for (i in 3..6 step 2) print(i)
-> 35

for (i in 'd'..'g') print (i)
-> defg

                                    val x = 3
when(x) {
    3 -> println("yes")
    8 -> println("no")
    else -> println("maybe")
}
// when can also be used as an expression!
val y = when(x) {
    3 -> "yes"
    8 -> "no"
    else -> "maybe"
}
println(y) // "yes"

                                    val array = arrayOf(1, 3, 9)
for (item in array) {
    //loops items
}
for (index in 0..array.size - 1) {
	//loops all indices
}
for (index in 0 untill array.size) {
    //loops all indices
}
for (index in array.indices) {
    //loops all indices (performs just as well as two examples above)
}
