I am just starting with Kotlin. I want to create range from 1 to n where n is excluded. I found out that Kotlin has ranges and I can use them as follows
1..n
但这是一个inclusive范围，包括1和n.如何创建exclusive个范围.

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 +1) to (upper bound - 1).
fun Int.exclusiveRangeTo(other: Int): IntRange = IntRange(this + 1, 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.
