Implementation of Removing Duplicates from a List

Merging Two Lists in Scala

Removing duplicates from a list involves eliminating duplicate elements to ensure each element appears only once in the resulting list. In Scala, you can achieve this by converting the list to a set and then back to a list, or by using the distinct method. Below is the Scala program to implement both the approaches:

Scala 
object HelloWorld {
   def main(args: Array[String]) {
      // Define a list with duplicate elements
      val listWithDuplicates = List(1, 2, 3, 2, 4, 3, 5);

      // Method 1: Using conversion to set and back to list
      val uniqueList1 = listWithDuplicates.toSet.toList;

      // Method 2: Using the distinct method
      val uniqueList2 = listWithDuplicates.distinct;

      // Display the unique lists
      println("Unique List (Using set conversion): " + uniqueList1);
      println("Unique List (Using distinct method): " + uniqueList2);

   }
}

Output:
