How to get Subset from a Set in Kotlin


How to get Subset from a Set in Kotlin ?

Answer

To get a sub Set in Kotlin, you can use the slice function with the range of indices.



✐ Examples

1 Get Sub Set with Items

In this example,

  1. We define a Set named mySet containing elements of a specific type.
  2. We specify the range of indices to extract the sub Set.
  3. We use the slice function with the specified range to get the sub Set.

Kotlin Program

fun main() {
    // Define Set with items
    val mySet = setOf("apple", "banana", "orange", "grape", "melon")

    // Get sub Set with items
    val subSet = mySet.slice(1..3)
    println("Sub Set with items: $subSet")
}

Output

Sub Set with items: [banana, orange, grape]

2 Get Sub Set from Empty Set

In this example,

  1. We define an empty Set named mySet.
  2. We attempt to get a sub Set from the empty Set, which results in an empty sub Set.

Kotlin Program

fun main() {
    // Define empty Set
    val mySet = emptySet<String>()

    // Get sub Set from empty Set
    val subSet = mySet.slice(1..3)
    println("Sub Set from empty Set: $subSet")
}

Output

Sub Set from empty Set: []
