How to get unique values from two arrays in Kotlin

Answer 1

fun get_unique_values(arr1: IntArray, arr2: IntArray): IntArray {
    val set1 = arr1.toSet()
    val set2 = arr2.toSet()

    val st = (set1 - set2) + (set2 - set1)
    
    return st.sorted().toIntArray()
}

fun main() {
    val arr1 = intArrayOf(1, 3, 6, 8, 12, 90)
    val arr2 = intArrayOf(2, 3, 5, 6, 7, 8, 96)

    val result = get_unique_values(arr1, arr2)
    println(result.joinToString(", "))
}


   
/*
