3.2.2多维数组 3.3 排序

 

例3.5 利用不规则的二维数组存储数据，输出杨辉三角形

//杨辉三角形
public class ArrayYanghui
{
    public static void main (String [] args)
    {
        int i, j;
        int yanghui[] []= {{1}, {1,1}, {1, 2, 1}, {1, 3, 3, 1}, {1,4,6,4,1}};
        for (i = 0; i < yanghui.length - i; i++)
        {
            for (j = 0; j < yanghui.length - i; j++)
                System.out.print(" ");
            for (j = 0; j < yanghui [i].length; j++)
                System.out.print (" "+yanghui [i] [j] + " ");
            System.out.println ();}
        System.out.println ();
    }
}
