K-Nearest Neighbor Algorithm

Below are the data points of classes A and B. Also, there is an unknown test data point for which the class is unknown. Use k-nearest neighbour algorithm to classify the unknown point as one of the two classes.

Class A = [(1,1), (2,1), (4,1), (2,2), (1,2.5)]

Class B = [ (3,1), (3, 1.5), (3, 2.5), (4,4), (2,4)]

Test points = (3.8, 1.2)

k = 3
