And then I have just one other drawing request which is if you could draw how an algorithm works. And I'll leave the phone so you can narrate what you're doing. Okay. I am not a computer scientist but let's say. Some if then statements or sort perhaps a different aspect of the drawing would be like just a bunch of inputs. Like how they teach you in school about a function. So, you have some inputs and then some function leads to your output. And so I guess the algorithm would be the function. Okay. Yeah, okay that's what I have. And where have you heard of the term algorithm before? I mean, in the world. I am a mathematician so I am somehow adjacent to - Ah, okay! and also I think just reading the news and yeah.
