I'm not sure if you want me to look at this PR yet - the CI build failure is a simple typo, the solution line CNOT(qs[0], q[1]); uses q instead of qs for the second argument, fixing it should fix the failure.

Thanks Mariia, I really should have spotted that typo that crept in somehow, but all's well now and it's ready for your perusal

Looks good! I did a bit of cleanup, and then realized that I didn't run the spellchecker on the last couple of solutions, so I did that - that's why you see some changes of the earlier workbook.

Thank you!
