◆Sum and Product
There are three integers such that 0<x<y<z<16. The sum of these numbers is
given to the mathematician A, and the product is given to the mathematician
B. These conditions are known by A, and B, and their task is to find these
three numbers. They make the following conversation:
A:"I can't find the numbers, and I can see that you can't find either."
B:"This is a helpful information, but still I can't find the numbers."
A:"Now I can find the numbers.”
What are the numbers?
Enter the values of x, y, z separated with commas.
有三個整數 x, y, z 滿足 0 < x < y < z < 16。
這些數的和給了數學家 A,而這些數的積給了數學家 B。
A 和 B 也都知道這個條件,而他們想要找出這三個數。
他們有了如下的對話:
A:「我不知道答案,而且我可以確定你也不知道。」
B:「這訊息很有幫助,但我還是不知道。」
A:「這樣的話我就知道了。」
試問此三數為何?
以 x,y,z 的格式作答,三數中間以逗號分隔。
