For each of the functions f(N) given below, indicate the tightest bound possible (in other words, otherwise specified, all logs are base 2). You MUST choose your answer from the following (not given in any particular order), each of which could be re-used (could be the answer for more than one of a)-h):
a) O(NlogN)
b) O(N)
c) O(N/2log2N)
d) O(NlogN)
e) O(N/3log(N+3N))
f) O(NlogN+1000+N^2)
g) O(N^3)
h) O(256logN)
