lookup table
Precomputed answer key
A lookup table is a data structure that maps input values to pre-computed output values, allowing quick retrieval instead of repeated calculation.
Rather than computing a result each time, you store answers in advance and simply look them up: The program uses a lookup table to convert color values.
Common in programming, electronics, and anywhere speed matters more than memory.
