12x3compactMap

12x3compactMap is a data structure or algorithm, likely found within a programming context, designed for efficient storage and retrieval of key-value pairs. The name suggests it handles a mapping of keys to values. The "12x3" part of the name might indicate a specific internal implementation detail, such as a fixed-size array of 12 elements, each potentially holding 3 sub-elements or pointers. This could imply a compact representation where memory usage is optimized. The "compactMap" portion reinforces the idea of a compact map implementation, which aims to reduce memory overhead compared to more general-purpose map structures like hash tables. Such structures are often used when memory is a critical constraint or when dealing with a known, relatively small, and fixed set of keys. The exact performance characteristics, such as lookup, insertion, and deletion times, would depend on the specific algorithm employed within this structure. It is likely designed to provide faster access than a simple linear search through a list, but potentially with limitations on dynamic resizing or the range of keys it can effectively handle.
