Stair Plot Beginner Problem

Hello,

I have been doing some beginner exercises for practice, but I am completely stuck on this one as I do not believe that's a simple square wave, meaning I do not know how to even start point a, let alone the rest of them.

If someone could provide the code / short explanations so a newbie can understand I would greatly appreciate it.

Look into the square function.

Consider adding two waves together to create the waveform shown.
