英语翻译
Roy has just moved into a new apartment.Well,actually the apartment itself is not very new,even dating back to the days before people had electricity in their houses.Because of this,Roy's apartment has only one single wall outlet,so Roy can only power one of his electrical appliances at a time.
Roy likes to watch TV as he works on his computer,and to listen to his HiFi system (on high volume) while he vacuums,so using just the single outlet is not an option.Actually,he wants to have all his appliances connected to a powered outlet,all the time.The answer,of course,is power strips,and Roy has some old ones that he used in his old apartment.However,that apartment had many more wall outlets,so he is not sure whether his power strips will provide him with enough outlets now.
Your task is to help Roy compute how many appliances he can provide with electricity,given a set of power strips.Note that without any power strips,Roy can power one single appliance through the wall outlet.Also,remember that a power strip has to be powered itself to be of any use.

罗伊刚搬进一间新的公寓.实话说,这所公寓并不是很新,甚至旧的可以追溯到人们开始在室内用电的年代以前.因此,罗伊的公寓只有一个壁装电源插座,这使得罗伊每次只能使用一台电器.
罗伊喜欢用电脑工作的时候看电视,也喜欢用他的音响放大音量的播放音乐的同时用真空吸尘器打扫卫生,所以单孔的墙上电源插座并不适合他.事实上,他想将他所有的电器一直连接到一个插座上.方法当然是用移动式插座啦.罗伊有很多在他以前的公寓住时用过的移动式插座.但是那间公寓有很多墙上电源插座,所以他不确定他的移动式插座能否提供足够的插孔.你的任务就是帮罗伊估算：给定的移动式插座能供多少电器足够的电力.请注意如果没有任何移动电源是插座,罗伊都可以通过墙上的电源插座给一台电器供电.还有,记住,一个移动式插座在给任何使用它的电器提供动力的同时也必须能为其自身提供动力.

不用这么急吧，还不给分，你也好意思

罗伊刚刚搬进一家新公寓。呃，其实，房子并不是新的，甚至古老的可以追溯到人们在室内没有用电的时代。因此，这个房子只有一个插座，而罗伊也只能每次用一个电器。
罗伊喜欢当他在电脑上工作的时候看电视。。。。。。。。。。。。
没分了。。...
