Creating exclusive ranges in kotlin
You can use the until function in the Kotlin stdlib:
for (i in 1 until 5) {
println(i)
}
Which will print:
1
2
3
4
Update 2022: Please use the built-in function until.
Old answer:
Not sure if this is the best way to do it but you can define an Int
extension which creates an IntRange
from (lower bound) to (upper bound - 1).
fun Int.exclusiveRangeTo(other: Int): IntRange = IntRange(this, other - 1)
And then use it in this way:
for (i in 1 exclusiveRangeTo n) { //... }
Here you can find more details about how ranges work.
