I just started this level and have no idea what some of these things mean. For instance:
What is “i”? How is it derived? What does it mean?
What is “j”? How is it defined? What are “points[j]” and “friends[j]”?
And lastly, what is “range(len(friends))”? I can read that this is the range of the length of the friends array, but what does that mean?
I’m pretty much stuck here at this level and can’t proceed until I get some answers and explanations. Even after watching the video tutorial I’m really lost and confused here.
