Another (stupid) question: "find first set" (or "find first zero")

[Marco Antoniotti]

 Hi

I am wasti....  devoting some time to recreational hacking and I bumped
into an interesting bit fiddling operation.

I pored over the CLHS, but, while I may have missed something obvious, I am
not sure what would be the best way to implement such a function using the
standard operations.

Any ideas?

Note that it appears that most HW does have an instruction to do that
directly.
Find first set - Wikipedia <https://en.wikipedia.org/wiki/Find_first_set>

Thanks
Marco
