Nope. Anything I publish will be available free.
This is done occasionally in algo books to encourage their adoption in cirricula (e.g. Dasgupta, etc.).
As a sibling comment mentions, it's relatively easy to verify your answer for correctness in some cases. The downside of this is that it becomes difficult to assess whether students are actually learning. One way to mitigate this is to withhold answers and assist with other teaching resources like TAs. This also helps teach the aforementioned 'verification' step.
