ProgramGuruTo create a set of size N in Kotlin, you can use the generateSequence function to generate a sequence and then convert it to a set using the toSet method.
In this example,
import kotlin.sequences.generateSequence.createSetOfSizeN that takes an integer n as a parameter. This parameter represents the desired size of the set.generateSequence function to generate a sequence of numbers starting from 1. The take method is used to limit the sequence to n elements.toSet method. This ensures that the resulting collection is a set with exactly n unique elements.main function, we call createSetOfSizeN with a specific size (e.g., 5) and store the result in a variable named mySet.println function.import kotlin.sequences.generateSequence
fun createSetOfSizeN(n: Int): Set<Int> {
return generateSequence(1) { it + 1 }.take(n).toSet()
}
fun main(args: Array<String>) {
val mySet = createSetOfSizeN(5)
println("Created set of size 5: $mySet")
}Created set of size 5: [1, 2, 3, 4, 5]
In this example,
import kotlin.random.Random.createRandomSetOfSizeN that takes an integer n as a parameter. This parameter represents the desired size of the set.resultSet to store the unique random numbers.while loop to repeatedly add random numbers to the set until its size equals n. The Random.nextInt function generates random integers.main function, we call createRandomSetOfSizeN with a specific size (e.g., 5) and store the result in a variable named myRandomSet.println function.import kotlin.random.Random
fun createRandomSetOfSizeN(n: Int): Set<Int> {
val resultSet = mutableSetOf<Int>()
while (resultSet.size < n) {
resultSet.add(Random.nextInt(1, 100))
}
return resultSet
}
fun main(args: Array<String>) {
val myRandomSet = createRandomSetOfSizeN(5)
println("Created set of size 5 with random numbers: $myRandomSet")
}Created set of size 5 with random numbers: [12, 47, 85, 24, 37]
In this tutorial, we learned How to create a Set of size N in Kotlin language with well detailed examples.
