You have input and output types of a function (its type |

The text does give a huge hint. I think it's fine but I know how to do it. |

For me, I could only make sense of this by looking at the code for x/tour/pic to figure out where dx & dy were coming from. Got to agree, this seems quite a leap for a beginner. Also, the description suggests you'll get to see the image as, y'know, a picture, but it seems it just outputs it as data? |

@lizrice I'm seeing the actual image.

|
@adg I can take a look at this one. |

@adg How about adding a slide that creates a tic tac toe game before we get to the Pic exercise? That would let us show a slice of slices in a slightly different setting. It's close enough to provide a good hint, but they'll still have to work out the looping for themselves. |
|
@kytrinyx I like it! |
|
Alright, I gave it a shot. I wasn't sure where to put it, so I added it immediately after the place where slices are introduced and described as |

The `Pic` exercise throws people a bit, since they've not seen the syntax for slices of slice. This shows syntax that is similar enough to provide a hint, without giving away the answer. They still have to figure out the assignment in the loop on their own.

at this point in the tutorial, we have not seen 2d arrays. absolutely no idea of how to make them.
also from the problem description, we have no idea of what you are meaning with the function examples.
this is just far too advanced for what a newbie knows
