What is the difference between Θ(n) and O(n)?
...for some values of c1 and c2, i.e. the growth rate of f is asymptotically equal to g: g can be a lower bound and and an upper bound of f. This directly implies f can be a lower bound and an upper bound of g as well. Consequently,
f(x) = Θ(g(x)) iff g(x) = Θ(f(x))
Similarly, to show f(n) = Θ...
