数组倒转
https://www.nowcoder.com/practice/3a90caee736a45e1ad70b1d4105dec5f
个人觉得这道题是要我们将数组中得数据反转
。
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......
for(int i = 0 ; i < 3 ; i ++){
int temp ;
temp = arr[i];
arr[i] = arr[arr.length - i - 1];
arr[arr.length - i - 1] = temp ;
}
System.out.println(Arrays.toString(arr));
}
}
。
