Webb14 juni 2024 · Decidability For the Recursive Language A language ‘L’ is said to be recursive if there exists a Turing Machine which will accept all the strings in ‘L’ and reject all the strings not in ‘L’. The TM will halt every time and give an answer either accepted or rejected for each and every input.
