Kotlin .slice()

In Kotlin, the .slice() function is used to create a new list containing elements from the specified range or indices of an array.

Syntax

array.slice(indices: IntRange): List<T>

Or, alternatively:

array.slice(indices: List<Int>): List<T>

• indices: IntRange: A range of indices from which the elements will be selected.
• indices: List<Int>: A list of specific indices representing the elements to be included in the new list.

Example

The following example demonstrates the usage of the .slice() function with both IntRange and List<Int>:

fun main() {
  val array = arrayOf(10, 20, 30, 40, 50)

  // Using IntRange to slice the array
  val sliceRange = array.slice(1..3) // Includes elements at indices 1, 2, and 3
  println("Slice using IntRange: $sliceRange")

  // Using List<Int> to slice the array
  val sliceList = array.slice(listOf(0, 2, 4))  // Selects elements at indices 0, 2, and 4
  println("Slice using List<Int>: $sliceList")
}

The above code produces the following output:

Slice using IntRange: [20, 30, 40]
Slice using List<Int>: [10, 30, 50]
