Now please draw how an algorithm works. [longer pause] Yeah, it works like this. Okay. Can you tell me about your drawing a little bit? Yeah, so in an algorithm, in my view, an algorithm takes something and gives an output of it. And then to do this, it does something on the input. And then what it does on the input can be defined by someone or it can be the algorithm like a mechanism in the nature, and you can figure it out, and then, for example, copied, as a algorithm, into a computer system. And then these are like individual little machines that constitutes a bigger machine that takes the input and gives the output. Is there a particular reason that you draw circles? Because I'm a mechanical engineer, and I thought of gears, and drawing full gears would take so much time. So you could imagine as them like gears. But the point is a gear would be too mechanical, so you can think of it something doing something, and then it is in connection with a different little unit. And then when you combine all these small systems, you can end up with a larger system, and then that system is going to do the same task over and over again when the same inputs are given. Okay. Thank you very much. Sure.
