打印数字图案的程序| Set

给定一个数字为’num’，行数为’num_of_lines’，其中’num’表示图案必须从中开始的起始编号，’num_of_lines’表示必须打印的行数。现在，根据以上信息，打印一个图案，如下所示。 例如：

null

Input: num = 7, num_of_lines = 4Output: 7        14 15        28 29 30 31        56 57 58 59 60 61 62 63Input: num = 3, num_of_lines = 3Output: 3        6 7        12 13 14 15

观察：

第一列的元素是该列中前一个元素的倍数。
每行中的元素数是前一行中元素数的两倍。
此外，要生成行中的下一个元素，请将1添加到该行的上一个元素。

方法： 因此，从0到num_of_line-1开始一个循环，以考虑要打印的行数，并在第一个循环中从0到limit-1开始另一个循环，limit将被初始化为1，其值呈指数增长。现在在循环中，只需将数字增加1，即可打印该行的下一个数字。
