2,3,6,8,9,15,18,22 ->break into 3 clusters

K1 = 2,8,18 mean: m1 = 9.3

K2 = 3,9,22 mean : m2 = 11.3

K3 = 6,15 mean : m3 = 10.5

Re-assign :

K1 = 2,3,6,8,9 mean: m1 = 5.6

K2 = mean : m2 = 0

K3 = 15,18,22 mean : m3 = 18.3

Re-assign :

K1 = 3,6,8,9 mean: m1 = 6.5

K2 = 2 mean : m2 = 2

K3 = 15,18,22 mean : m3 = 18.3

Re-assign :

K1 = 6,8,9 mean: m1 = 7.5

K2 = 2,3 mean : m2 = 2.5

K3 = 15,18,22 mean : m3 = 18.3

Re-assign :

K1 = 6,8,9 mean: m1 = 7.5

K2 = 2,3 mean : m2 = 2.5

K3 = 15,18,22 mean : m3 = 18.3

Last two groups are same. So finally we got 3 clusters

Cluster1 = {6,8,9} Cluster2 = {2,3} Cluster3 = {15,18,22}
