Hi everyone, my first post here. Have had a good look round first and like what I see
Alas, first post and I am asking for help in solving this !!!
What happens if we ask "If I asked your friend whether this path is safe what would he answer?"
You must consider four cases.
1) Paqoko answering about the safe path.
2) Paqoko answering about the deadly path.
3) Oldiwalla answering about the safe path.
4) Oldiwalla answering about the deadly path.
Work out the pattern for those four and you will see your strategy is obvious.
In this case it is more reliable to try to structure answers based on ( + - ) and ( - + ), than to try to get ( + + ) and ( - - ) if you see what I mean.
Many thanks - Marts
