有乘法算式如下：
○○○
× ○○
------------
○○○○
○○○○
------------
○○○○○
18个○的位置上全部是素数(1、3、5或7)，请还原此算式。
*问题分析与算法设计
问题中虽然有18数位，但只要确定乘数和被乘数后经过计算
就可确定其它的数位。-multiplication formula is as follows : 2000 2000------ 2000 2000------ 2000 18 hours position all prime numbers (1, 3, 5 or 7), this reduction formula.* Analysis and design of algorithms Although the number of 18-bit, but as long as the multiplicand and multiplier determined after a calculation can be determined by several other.
