An implementation of these things may make use of sentinel nodes to reduce off-by-one errors.
Like loops, these things are often unrolled such that the items stored within them fit into a single unit of memory to improve cache performance. In some programming languages, the map function takes two inputs, one of these objects and a function, and then outputs another of these objects. An implementation of these things may make use of sentinel nodes to reduce off-by-one errors. In Python, these objects may be built using a namesake notation that resembles (*)  set-builder notation; also in Python, the "zip" function returns a single one of these objects whose elements are tuples. Pointers that refer to "previous" nodes and "next" nodes are used in the "doubly-linked" variety of these structures. For 10 points, name these objects that consist of a sequential collection of data.
