THE MAPPING FROM INPUTS TO OUTPUTS IS BY FINITE STRING TRANSFORMATIONS. The mapping to compute the sum function is from integers transformed by the steps of arithmetic to an integer OUTPUT. int sum(int x, int y) { return 5; } The above mapping IS NOT for the sum function. -- Copyright 2025 Olcott "Talent hits a target no one else can hit; Genius hits a target no one else can see."
