How to find the uncommon elements from two arrays in Scala

Answer 1

import scala.collection.mutable.ArrayBuffer

object Main extends App {
  val arr1 = Array(1, 2, 7, 5, 16, 19, 18)
  val arr2 = Array(1, 8, 5, 12, 19, 52, 103, 150)

  val uncommonArr1 = arr1.filterNot(arr2.contains)
  val uncommonArr2 = arr2.filterNot(arr1.contains)

  val uncommon = uncommonArr1 ++ uncommonArr2

  println(uncommon.mkString(", "))
}


 
 
/*
run:
   
2, 7, 16, 18, 8, 12, 52, 103, 150
 
*/
