Ranges
Kotlin provide a way to deal with value ranges, so you might be able to simply create and manipulate ranges effortlessly.
Control if a value belong or not to a range of elements.
// { autofold
fun checkRange(i: Int) {
//}
if (i in 1..10) { // equivalent of 1 <= i && i <= 10
println("$i belongs to the range 1..10")
}
// { autofold
}
fun main(args: Array<String>) {
checkRange(1)
Iteration over ranges
// { autofold
fun main(args: Array<String>) {
//}
for (i in 1..5) println("square($i) gives ${i * i}")
// { autofold
}
//}
Reverse iteration over ranges
// { autofold
fun main(args: Array<String>) {
//}
for (i in 5 downTo 1) print(i)
// { autofold
}
//}
Iterating over ranges ... step by step
// { autofold
fun main(args: Array<String>) {
//}
for (i in 1..10 step 2) print(i)
// { autofold
println()
// }
for (i in 10 downTo 1 step 2) print(i)
// { autofold
}
Range with exclusion
// { autofold
fun main(args: Array<String>) {
//}
for (i in 1 until 5) print(i)
// { autofold
}
//}
