Suppose that a dynamic set $S$ is represented by a direct-address table $T$ of length $m$. Describe a procedure that finds a maximum element of $S$. What is the worst-case performance of your procedure?
We start with the bottom of the table (the largest element) and scan the table backwards until we find a slot that contains an element. The worst case performance is $\Theta(m)$, if the maximum element is in the first position of the table (or the dynamic set is empty).
