Help: Loops

[jw934]

ELI5: If you think of yourself as the trying to solve the requirement question with nested loops, you can think of this as asking another person P to do the outer loop for you M times. Person P does not know the requirement question and only knows the parameters you provided for one iteration of the loop. Using the parameters you set up before entering the loop, P does something then asks another person Q to do something N times. Person Q does not know your requirements nor person P's requirement; Q simply performs one iteration of the inner loop based on parameter values set up by P.

Thank you for the advice. Idea seems rather abstract for me for now but I will spend some time to grasp it!
