If it's a small toy with a $0.20 microcontroller in it, where all the software does is blinking a LED, then yes, it's possible. But most software is way more complex than that. – vsz Oct 21, 2024 at 4:41 60

"In theoretical computer science, an algorithm is correct with respect to a specification if it behaves as specified. Best explored is functional correctness, which refers to the input-output behavior of the algorithm (i.e., for each input it produces an output satisfying the specification). Within the latter notion, partial correctness, requiring that if an answer is returned it will be correct, is distinguished from total correctness, which additionally requires that an answer is eventually r… " - Provably correct programs
