The 'thorn in my flesh'... (Big (O)) Have i understood it right? lazarus / 8-Other ---------------------------------------------------------------------- timtims33 · 2015-12-15 20:37 Hi, Been learning about Big(O) and making my own notes on the basics of it. I've compiled it down to three pages but want someone who knows the stuff to look at my brief notes and tell me if my understanding is correct. Don't know if this is the right 'forum' to be asking for a proof-read...but will at least ask the question anyway. I'm uncertain about the O(n^2) on page 2...i've highlighted it.  Document is attached for anyone who is keen enough to check my understanding. thanks, t
