输入n个数,然后倒着输出来:
import java.util.*;
public class Main {
static Scanner cin = new Scanner(System.in);
static void dfs(int n) {
if(n>0) {
int x=cin.nextInt();
dfs(n-1);
System.out.print(x+" ");
}
}
public static void main(String[] args){
int n=cin.nextInt();
dfs(n);
}
/*输入n个数,然后倒着输出来
5
3 2 1 4 5
5 4 1 2 3
