WebMar 27, 2016 · I'm using the fact that every recursive language is recursively enumerable, and the well-known closure properties of RE languages. (A) L2 - L1 = L2 intersection (complement L1) is recursively enumerable because L1 is recursive, thus (complement L1) is recursively enumerable, and an intersection of RE languages is again a RE language.

WebIn mathematics and computer science, a class of objects or methods exhibits recursive behavior when it can be defined by two properties: A simple base case (or cases) — a terminating scenario that does not use recursion to produce an answer; A recursive step — a set of rules that reduces all successive cases toward the base case.; For example, the … keurig and regular coffee maker comboWeb: Formally establishing safety properties of software presents a grand challenge to the computer science community.
