Import the $$Unsupervised$$ data set into a dataframe in R$.$ a$-$ Pre$-$process this data set based on what you have learned throughout the course. b$-$ Use the K$-$means method to cluster the $77$ observations into five clusters. Find a proper way to visualize the resulting clusters. c$-$ Use the hierarchical clustering method to cluster the $77$ observations, using the Euclidean distance with single linkage. Visualize the results and comment on the outcome.
