i feel dumb but what is 0(1) and 0(N). im trying to glean from the context but all ive gotten that 0(1)~=good/easy/effcient and 0(N)~=bad.

Edit: other than that, not a bad read. for more tip ideas i was thinking a more in depth explaination on pointers and functional uses for them. also I got the idea while reading this that it might be good at some point to have a small article about the different ways to modify a data structure (que's, deque's, stack's, popping, pulling, etc.)
