[EX Q]: The layout of this painting mirrors the plan for St. Peter's Basilica. In the center of this painting, a man wearing a purple shirt slumps against a box, scribbling on a sheet of paper at the bottom of some stairs.

[EX Q]: One potential issue with these objects can be obviated with the tortoise-and-hare algorithm or Floyds circle-finding algorithm, which is a linear-time procedure for finding loops. The amortized runtime for most operations on these structures can be reduced by building an array on each container, or by building-up from one of these a multi-level parallel series of them; those are the techniques of unrolling and skip creation. If the ends of these are protected with self-referential containers called sentinels, they are not prone to cause addressing faults, which usually result from moving past the end. Uni-directional iterators were created to work with these data structures, which are commonly implemented as objects containing a value and a pointer to an object of the same kind. For ten points, name these data structures idealized as series of chained nodes.
