Sinopsis

Please note that the content of this book primarily consists of articles available from Wikipedia or other free sources online. In computer science, a lookup table is a data structure, usually an array or associative array, often used to replace a runtime computation with a simpler array indexing operation. The savings in terms of processing time can be significant, since retrieving a value from memory is often faster than undergoing an ''expensive'' computation or input/output operation. The tables may be precalculated and stored in static program storage or calculated as part of a programs initialization phase.
