Problem 1189. Knights and Knaves (part 3)
If the guard is a knave, and I ask him what the password is, what response do I get? Do I still get an array of chars? Does he replace 'A' with 'Z', 'B' with 'Y', etc..?
questions can only be statements that evaluate to a scalar logical value (yes/no questions), so you can ask things like QUESTION('PASSWORD(1)==''A'''); or QUESTION('strcmp(PASSWORD,''ASDF'')'); but if you ask a question that returns a vector you will simply get an error.
Very fun problem Thanks!
Thank you for taking the time to make up this series of problems.
