99,k4是32的倍数.问k被32除的余数可能是? (I) 2(II) 4(III) 6 (提供者ID:jacinth17。) 思路:32=2^5,k的可能取值是2^2,2^3,2^4,2^5及32的倍数。2^5及32的倍数直接整除,不考虑。有余数的取值,只有2^2,2^3,2^4,算出来,答案中只有符合 九十四 有w个workers, each is sent to one of three departments. If w is divided by 3, the remainder is 1. 问how to distribute the workers to the three departments?
(提供者ID:jacinth17。原文:答案选(w-1)/3、(w-1)/3、(w+2)/3) 这两道题都是嘛意思啊,求NN解释~~~
