Hi guys; I'm so confused on how the lecturer said that a problem is like a circle and can dividing it to sub-problems which we can visualize it by dividing a circle to some parts (lets say to three parts which each part generate angle 120) but what's confusing me that between one part of circle and other part there's a line "line which's separate one part from other part" my question is, this line is jointed between one part and other part .. so once we solve a sub problem in one part .. it's still a part from the other part because the line is mutual between two parts, so what's confused me those lines what are they? are they meaning something?! sorry about that but those lines make my all confusion in everyproblem.. how should I consider those lines which dividing a circle to three parts to visualize that we right now need to solve three sub-problem which generate a problem ..
thanks for your help in advance.
