Scala Stack distinct() method with example

In Scala Stack class, the distinct() method is utilized to delete the duplicate elements from the given stack.

Method Definition: def distinct: Stack[A]

Return Type: It returns a new stack with only distinct elements.

Example #1:

// Scala program of distinct()
// method

// Import Stack
import scala.collection.mutable._

// Creating object
object GfG
{

    // Main method
    def main(args:Array[String])
    {

        // Creating stack
        val s1 = Stack(1, 3, 2, 1, 2, 1, 3, 2, 3, 3)

        // Print the stack
        println(s1)

        // Applying distinct() method
        val result = s1.distinct

        // Display output
        print("Stack with distinct elements: " + result)

    }
}

Output:

Stack(1, 3, 2, 1, 2, 1, 3, 2, 3, 3)
Stack with distinct elements: Stack(1, 3, 2)

Example #2:

// Scala program of distinct()
// method

// Import Stack
import scala.collection.mutable._

// Creating object
object GfG
{

    // Main method
    def main(args:Array[String])
    {

        // Creating stack
        val s1 = Stack("g", "e", "e", "k", "s", "f", "o", "r", "g", "e", "e", "k", "s")

        // Print the stack
        println(s1)

        // Applying distinct() method
        val result = s1.distinct

        // Display output
        print("Stack with distinct elements: " + result)

    }
}

Output:

Stack(g, e, e, k, s, f, o, r, g, e, e, k, s)
Stack with distinct elements: Stack(g, e, k, s, f, o, r)
