KNN. Consider the following one-dimensional dataset. Each example is described by one numerical feature x and has a discrete label y{-, +}.

X	1	2	3	4	5	6	7	8	9	10
Y	-	-	-	+	+	+	+	-	-	-

Consider x 0, 12. What is the output of a 1-NN (nearest neighbor classifier)? Provide ALL the intervals in [0, 12] labeled 1. For example, [6, 7] is labeled 1. In case of ties, choose the point on the left. Show all your steps.
