Hierarchical clustering is sometimes used to generate K clusters, K > 1 bytaking the clusters at the Kth level of the dendrogram. (Root is at level1.)The following is a set of one dimensional points: {0, 3, 6, 12, 18, 24, 30,42, 48, 60, 70}

a. For the centroid {18,45} create two clusters.
b. For the centroid {8, 20, 40} create three clusters
c. For centroid {2, 10, 30, 40} create four clusters
