[Prоblem V: Hierаrchicаl Clustering] (Extrа credit: 3 pоints). Cоnsider the phylogenetic tree we built using Euclidean distance and complete linkage. Let C1 denote the cluster consisting of Sub2 and Sub12.Let C2 denote the cluster consisting of Sub5 and Sub8. According to the complete linkage, what is the distance between C1 and C2? For your convenience, the distance matrix for the four subjects is shown below.
