I used to be working my manner by some Knight and Knave Puzzles in Discrete Maths by Rosen, after I got here throughout the next query:

There are inhabitants of an island on which there are three sorts of individuals:

• Knights who at all times inform the reality

• Knaves who at all times lie

• Spies who can both lie or inform the reality.

You encounter three folks, A, B, and C.

You know certainly one of these folks is a knight, one is a knave, and one is a spy.

Each of the three folks is aware of the kind of particular person every of different two is.

For this case, if attainable, decide whether or not there’s a distinctive answer and decide who the knave, knight, and spy is:

A says "C is the knave,” B says, “A is the knight,” and C says “I am the spy"

My Solution:

Doubt:

Am I right in saying my reply will work?
