public class SwapArr {
    public static void main(String[] args) {
        int[] arr={1,2,3,4, 5};

        System.out.println(Arrays.toString(arr));
    }
    static void reverse(int[] arr){
        int start = 0;
        int end = arr.length - 1;

        while (start<end){
            swap(arr,start,end);
            start++;
            end--;
        }
    }
    static void swap(int[] array,int firstIndex, int secondIndex){
        array[firstIndex] = array[firstIndex] ^array[secondIndex];
        array[secondIndex] = array[firstIndex] ^array[secondIndex];
        array[firstIndex] = array[firstIndex] ^array[secondIndex];
