Ask questions about two algorithms. 1. it is known that the width of the rectangle O is $ ow and the height is $ oh. when the O ratio remains unchanged, the O is scaled to a width not greater than $ dw, and the height not greater than $ dh, for the rectangle D with the largest area, calculate the width of the rectangle D $ nw and the height $ nh2.a. implement the function functionprint ($ m, $ n); $ m is the row, $ n is the column, and returns a two-dimensional array. ask questions about the two algorithms for the format.

Is this assignment assigned by the school teacher?
Think about it. it's not too difficult to clarify your ideas.
1: just take an equal ratio formula and make a decision.
2: The Law of even and odd rows
3: just like the above, you can find the maximum number.
------ Solution --------------------
PHP code
$a){ $arr[$k]=array_reverse($a); } return $arr;}print_r(convert($array));
