It would be great if there were some hints that were specific to each problem in here to nudge us in the right direction. Going to the discussion page normally just has the answers and the Article pages dont give much outside of the basic concepts. Some nice leveled hints behind a spoiler tag would really help me get into though process of solving these questions on my own much more than essentially "cheating" and looking at the answers and reverse engineering.

Understanding what a Queue and BFS is conceptually is good, but being able to learn how to approach a problem and answer it with a queue or BFS would be much more meaningful to learn. Going from "Here is the definition and manual implementation of a queue" directly to solving "Number of Islands" and "Open the Lock" is whiplash and im not learning much other than the feeling of guilt when i go to discussions.
