When the reverse () function is executed, first check if the grades string is empty. If it is, we return the list of grades to the main program. This stops the recursion because the reverse () call at the end of the function is not given the chance to run.

Webbin recursion theory. The first systematic use of the universal property in functional programming was by Malcolm (1990a), in his generalisation of Bird and Meerten’s theory of lists (Bird, 1989; Meertens, 1983) to arbitrary regular datatypes. For finite lists, the universal property of fold can be stated as the following equivalence Webbhavioural theory ofsequential recursive algorithms. For thiswe proposean axiomatic definition of sequential recursive algorithms which enriches sequential algorithms by call steps, such that the parent-child relationship between caller and callee defines well-defined shared locations representing input and return parameters.

WebbSince 1944, and especially since 1950, the subject of recursive function theory has grown rapidly. Many researchers have been active.
