Kotlin: create a map from a list using index

Question

I have a list as follows:

val numbers = listOf("one", "two", "three", "four")

I want to create a map such that each index goes to each value of the list.

1 to "one", 2 to "two", ..

I want the result to be a

Map<Int, String>

Answer 1

One of the ways could be:

numbers.mapIndexed { index: Int, s: String -> index + 1 to s }.toMap()
