inline fun <R, C : MutableCollection<in R>> CharArray.mapIndexedTo(destination: C, transform: (index: Int, Char) -> R): C(source)

Applies the given transform function to each element and its index in the original array and appends the results to the given destination.

Parameters

transform

function that takes the index of an element and the element itself and returns the result of the transform applied to the element.

inline fun <T, R, C : MutableCollection<in R>> Iterable<T>.mapIndexedTo(destination: C, transform: (index: Int, T) -> R): C(source)

Applies the given transform function to each element and its index in the original collection and appends the results to the given destination.

Parameters

transform

function that takes the index of an element and the element itself and returns the result of the transform applied to the element.
