During a research work, you found $7$ observations as described with the

data points below. You want to create $3$ clusters from these observations

using K$-$means algorithm. After first iteration, the clusters C$1,$ C$2,$ C$3$

has following observations:

C$1$: $\{(2,2),(4,4),(6,6)\}$

C$2$: $\{(0,4),(4,0)\}$

C$3$: $\{(5,5),(9,9)\}$

If you want to run a second and third iteration then what will be the

centroids?
