How to merge two sorted arrays without duplicates in Scala

Answer 1

def merge(arr1: Array[Int], arr2: Array[Int]): Array[Int] = {
  val mergedSet = (arr1 ++ arr2).toSet
  
  mergedSet.toArray
}

val arr1 = Array(1, 2, 2, 3, 7, 7, 7, 8, 9)
val arr2 = Array(0, 0, 4, 4, 4, 5, 6, 7, 7, 8)

val mergedArray = merge(arr1, arr2)

val sortedArray = mergedArray.sorted

println(sortedArray.mkString(", "))



/*
run:

0, 1, 2, 3, 4, 5, 6, 7, 8, 9

*/
