What were precomputed tables and why were they necessary?
Precomputation in algorithms refers to the act of running an initial computation ahead of run time to create a lookup table that may be used by an algorithm to avoid running the same computation repeatedly each time it is executed.
What is algorithm?An algorithm is a process used to carry out a computation or solve a problem. In either hardware-based or software-based routines, algorithms function as a detailed sequence of instructions that carry out predetermined operations sequentially.
Algorithms are procedures for resolving issues or carrying out tasks. Algorithms include math equations and recipes.
Algorithms are used in programming. All online searching is done using algorithms, which power the internet.
The term "precomputation" in the context of algorithms refers to the act of performing an initial computation before the algorithm is actually used.
This creates a lookup table that the algorithm can utilise to avoid performing the same computation repeatedly each time it is used.
Thus, this way, precomputed tables are essential.
