A certain list consists of several different integers .Is the product of all the integers in the list positive?
(1) The product of the greatest and the smallest of the integers in the list is positive.
(2)There is even number of integers in the list.
答案看以前的讨论是C
可是0是不是integer呢?
如果0是interger 那么应该是E?
我哪里错啦
