Suppose we are doing k-means clustering for k=2 on the following 6 points in R2 : (6,5),(1,4),(5,3),(1,1),(1,8),(5,6) and it is initialized with two centers at (1,4),(1,8). Compute the following for the first iteration: A: The centers that each of the other 4 points get assigned to. B: The new centers computed for the following iteration
