On a certain island there live only knights, who always tell the truth, and knaves, who always lie.
One day you find 10 island natives standing in a circle. Each one states: "Both people next to me are knaves!"
Of the 10 in the circle, what is the minimum possible number of knights?

If four of them are Knights, it can be true (KkkKkkKkKk...)
