Consider the following functions: F(n) = 2ⁿ
G(n) = n!
H(n) = n^logn
Which of the following statements about the asymptotic behaviour of f(n), g(n), and h(n) is true?

f(n) = O (g(n)); g(n) = O(h(n))

f(n) = $$\Omega$$ (g(n)); g(n) = O(h(n))

g(n) = O (f(n)); h(n) = O(f(n))

h(n) = O (f(n)); g(n) = $$\Omega$$ (f(n))

You are given the post order traversal, P, of a binary search tree on the n element, 1,2,....,n. You have to determine the unique binary search tree that has P as its post order traversal. What is the time complexity of the most efficient algorithm for doing this?

$$\Theta \,(\log n)$$

$$\Theta \,(n)$$

$$\Theta \,(n\log n)$$

None of the above, as the tree cannot be uniquely determined.
