Just referring back to another previous post, why is the 1 still there, and why has the video suddenly stopped at timestamp 2:54, without any sound, and skipped to a part which is disconnected from the previous part of the video?
I read the solution to the mini problem and understood, but I didn't really get the process: why do the two squares/rectangles have to touch at one particular point? For some reason I thought of it as three 2x2 squares for the mini-problem...😂
