hey folks, just wanted to share a little brain teaser i came across today. it’s called the “knights and knaves” puzzle. basically, imagine you're on an island with two types of people: knights who always tell the truth and knaves who always lie. you meet two islanders, and one says, “at least one of us is a knave.” who’s who? took me a while to figure it out but it's a fun exercise for those critical thinking muscles. give it a shot and let me know what you think!
