CSC165 WEEK7

This week we recapped the formal definitions of asymptotic notations O(f(n)) and Ω( f(n) ).I think they are not difficulty to understand, and the core of solving related proofs is to find the C and B(breakpoint)so that we can get the upper or lower bound. But I am wondering that why we paid so much attention to them. I know we can use them to analyse the running time of the programming code, but I think we don't care to much about the method of calculation of the running time in csc165, since I remember it is required in CSC108. 

And we are gonna take a test again next week! OMG I just finished my midterms on this Friday! Hope it won't be too challenging.
