Find majority labels in each cluster, for different k values, respectively. For example, if there are k = 2 clusters, and their labels are {0, 1, 1, 1} and {0, 0, 1} then the majority label for the first cluster is 1 and for the second cluster is 0. It is required you implement the algorithms yourself rather than calling from a package.
