蛇行矩阵 （Java代码）

解题思路:

注意事项:

参考代码:

public static int f(int m)

{

     if(m==0) return 1;

     return f(m-1)+m;

}

public static void main(String[] args)

{

     Scanner sc = new Scanner(System.in);

     int a = sc.nextInt();

     for(int i = 0;i<a;i++)

     {

         int m = f(i);

         System.out.print(m+" ");

         int n = m;

         int ii = i;

         for(int j = a-1;j>i;j--)

         {

             n +=(ii+2);

             ii+=1;

             if(j==i+1)

             {

                  System.out.print(n);

             }

         else System.out.print(n+" ");

     }

     System.out.println();

     }

}
