A very special island is inhabited only by knights and knaves. Knights always tell the truth, and knaves always lie.
Nine inhabitants of the island: Mel, Bart, Sue, Betty, Rex, Zeke, Sally, Zoey and Homer are busy at a conversation. A visitor from a neighboring island stopped by and asked each of the nine inhabitants their respective identities. They say:
Mel: "Only a knave would say that Sally is a knave."
Bart: "Rex is a knave."
Sue: "Mel and Homer are knaves."
Betty: "I know that I am a knight and that Sally is a knave."
Rex : "Betty and I are both knights."
Zeke: "At least one of the following is true: that Sally is a knight or that Sue is a knight."
Sally: "It's false that Betty is a knave."
Zoey: "It's not the case that Sue is a knave."
Homer: "Betty is a knave or Zeke is a knave."
Determine the type of each of the inhabitants from the abovementioned statements.
