Solving these problems (almost) every day and then watch your videos. It really helps to better wrap your mind around the solution and gain a better understanding of the technique used. Your abstract comments like "the lesson here is..." help to generalize the idea and then use it in the next problems. Thank you!

You HAVE been a GREAT help, Errichto. But I still had problems solving this question. Will go back to your 3rd video and re-visit what you said there.
