Disjoint set forest

The concept of the disjoint set forest was introduced by Bernard A. Galler and Michael J. Fischer in 1964. The disjoint set forest is a method of implementing disjoint sets quickly. In the disjoint-set forest, each tree member points only to its parent. The root of every tree includes its representative and its parent. The disjoint set forest is a special kind of forest that performs Union and Find operations in near-constant amortized time.

QUESTION ONE Use the k-means algorithm and Euclidean distance to cluster the following samples into 3 clusters: A1= (2,10), A2= (2,5), A3= (8,4), A4= (5,8), A5= (7,5), A6= (6,4), A7= (1,2), A8= (4,9). Suppose that the initial seeds (centers of each cluster) are A1, A4 and A7. Run the k-means algorithm for 1 epoch only. At the end of this epoch show: (i)The new clusters (i.e. the examples belonging to each cluster The centers of the new clusters Draw a 10 by 10 space with all the 8 points and show the clusters after the first epoch and the new centroids.
