Seems legit to me.

anonymous · Answer

I need another example other than the one that's given

hero · Answer

Oh, I see.

anonymous · Answer

Do you know one? by any chance?

hero · Answer

Well, I had one. I was going to say vacuum with a reverse switch, but now I'm having trouble coming up with the input and output.

anonymous · Answer

read this The washer takes dry clothes as input and outputs wet clothes.  A dryer takes wet clothes as the input and returns dry clothes.

anonymous · Answer

think of a vacuum im trying to think of it too

hero · Answer

The basis of operation for a vacuum is an air pump that has a suction and a discharge. When you flip the reverse switch, the discharge becomes the suction, and the suction becomes the discharge.

anonymous · Answer

I guess what could be said is the vacuum takes in garbage and dust as input. The reverse switch takes the garbage and dust input and returns garbage and dust?

hero · Answer

I think you should just go solely with the pump analogy rather than connect it with the operation of a vacuum.

hero · Answer

Because if you put the vacuum in reverse, it acts as a blower but it doesn't blow debris out of it.

hero · Answer

Yeah, just use the analogy of a pump with suction and discharge.

anonymous · Answer

so use a pump instead of a vacuum cleaner?

hero · Answer

Yes, it is best to just solely go with the concept of a pump, but I'll have to double-check the specific kind of pump.

anonymous · Answer

Oh ok well once we both figure out what kind of pump xD ill type up my final answer lol. Do pumps have a reverse button as well? im kind of confused on what a pump is.

hero · Answer

Maybe a hair blower would be an alternative. If I'm not mistaken, hair blowers have such a feature where you can put it in reverse.

anonymous · Answer

What would be the input of the hair blower?  is the hair blower like a blow dryer?

hero · Answer

Yeah, that's what I meant. Hair dryer.

anonymous · Answer

Well the thing  for this problem is that by input is that something has to go into it. Like the example used above was a washing machine they used clothes as the input.

hero · Answer

Okay, scratch all previous ones I mentioned. I have confirmation that water pumps definitely have this feature.

hero · Answer

A water pump is what you should go with.

anonymous · Answer

what's the input for a water pump? water?

hero · Answer

yes

hero · Answer

Well, I guess that isn't a good example either.

anonymous · Answer

Im wondering if I have to use two items that work together. Like a washer and a dryer. What are two items that we use in every day life that work together?

hero · Answer

I'll have to think about it.

anonymous · Answer

Ok ill be think too.

anonymous · Answer

hero · Answer

I'll have something in about 10 minutes.

anonymous · Answer
