$K$-mean clustering algorithm has clustered the given $8$ observations into $3$ clusters after $1^{st}$ iteration as follows:
$C1:{(3,3),(5,5),(7,7)}$
$C2:{(0,6),(6,0),(3,0)}$
$C3:{(8,8),(4,4)}$
What will be the Manhattan distance for observation $(4,4)$ from cluster centroid $C1$ in second iteration?
