Normal and reverse iteration through a vector:
Elements in normal (forward) order:  2  3  5  7  11
Elements in reverse order:           11  7  5  3  2
Normal and reverse iteration through a list:
Elements in normal (forward) order:  2  3  5  7  11
Elements in reverse order:           11  7  5  3  2
