Running times represented using the Big-Oh notation are interested in:
A) an upper-bound running time.
B) as tight an upper bound as possible.
C) a condition such that for an n sufficiently big, the expression inside Big-Oh is a lower bound of the running time.
D) All of these are correct.

Question

Quizplus · Accepted Answer

Big-Oh notation is used to describe the upper bound of a function's running time. The goal is to find the tightest upper bound possible, which means that the expression inside the Big-Oh notation should be as small as possible while still being an upper bound. Additionally, Big-Oh notation is not concerned with lower bounds, so option C is incorrect.
