find the unique elements in two arrays in Go

package main

import "fmt"

func main() {
	arr1 := []int{1, 2, 4, 5, 6, 7}
	arr2 := []int{2, 3, 4, 7, 8}
	
	//to store the unique element
	var result []int

	//loop to check if arr2 elements are present in arr1
	for _, v := range arr2 {
		found := false
		for _, i := range arr1 {
			if v == i {
				found = true
				break
			}
		}
		
		//add to the result arr if not found in arr1
		if !found {
			result = append(result, v)
		}
	}

	fmt.Println(result)
}

This code finds the unique elements in two arrays. First, two arrays, arr1 and arr2, are declared with elements in them. Second, a new array named ‘result’ is declared to store the unique elements. Then, a loop is used to go through each element of array2 and check whether it is present in array1. If it is present, the loop moves to the next value; if the element is not present, it is appended to the result array. Finally, the result array is printed with the unique elements of the two arrays.
