import java.util.Arrays; import java.util.Scanner;

public class Main { public static void main(String[] args) { int[] arr = new int[6]; Scanner scanner = new Scanner(System.in); for (int i = 0; i < arr.length; i++) { arr[i] = scanner.nextInt(); } System.out.println(Arrays.toString(arr));

    //write your code here......
    int length = arr.length;//数组的长度
    int len = length/2;//数组的中间索引下标
    int temp = 0;
    //遍历数组的前半部分，将前半部分与后半部分互换
    for(int i=0;i<len;i++){//数组倒置
        temp = arr[i];
        arr[i] = arr[length-1-i];
        arr[length-1-i] = temp;
    }

    System.out.println(Arrays.toString(arr));
}
