一个很难的数学问题（智力140以下勿进） 旧版Java程序设计Page97 3.12题 庞涓拿到两个整数（2到99之间）之和，孙膑拿到两个整数之积。下面是一段很有趣的对话。 庞涓说：我不知道这两个整数是多少，但我肯定你也不知道。 孙膑说：我本来不知道这两个整数是多少。但既然你这么说，那我现在知道了。 庞涓说：哦，那我也知道了。 要求输出所有可能的结果，包括这两个整数之和以及这两个整数之积。 程序设计思路：通过庞涓和孙膑的对话，逐步缩小和的范围，直至得出答案！-A difficult mathematical problem (intelligence not to enter the following 140) old Java programming Page97 3.12 title Pang Juan got two integers (2 to 99) the sum, Sun Bin 2 integers to get the product. Here is a very interesting dialogue. Pang Juan wrote: I do not know how much these two integers, but I am sure you do not know. Sun Bin said: I did not know how much of these two integers. However, as you say so, then I now know. Pang Juan said: Oh, I know. Require the output of all possible results, including the sum of these two integers, as well as the product of these two integers. Program design ideas: By Pang Juan and Sun Bin dialogue, gradually narrowing the scope of, and until the answer!
