WebYour algorithm is correct, and so is the algorithm that ml0105 gave. But whichever algorithm you use, you will certainly need two nested inductions. I will prove your algorithm but exactly the same structure can be used to prove the other algorithm. WebThe proof consists of three steps: first prove that insert is correct, then prove that isort' is correct, and finally prove that isort is correct. Each step relies on the result from the previous step. The first two steps require proofs by induction (because the functions in question are recursive). The last step is straightforward.
