Question

How to find the uncommon elements from two arrays in Go

Answer 1

package main

import (
	"fmt"
)

func main() {
	arr1 := []int{1, 2, 7, 5, 16, 18}
	arr2 := []int{1, 8, 5, 12, 19, 52, 103, 150}

	uncommonArr1 := filter(arr1, arr2)
	uncommonArr2 := filter(arr2, arr1)

	uncommon := append(uncommonArr1, uncommonArr2...)

	fmt.Println(uncommon)
}

func filter(arr1, arr2 []int) []int {
	var result []int
	for _, obj := range arr1 {
		if !contains(arr2, obj) {
			result = append(result, obj)
		}
	}
	return result
}

func contains(arr []int, obj int) bool {
	for _, v := range arr {
		if v == obj {
			return true
		}
	}
	return false
}
