In this prоblem, we hаve sketched up the cоde fоr the K-Meаns Clustering аlgorithm. Please choose options to fill in the blanks. import numpy as np import matplotlib.pyplot as plt def kmeans(X,K,iteration):     N = len(X) # Number of data points     labels = np.zeros((N,1)) # Cluster labels for each data point     centroids = np.zeros((K,X.shape[1])) # Centroid of each cluster     # Innitialize: Randomly assign a number C(i) in (1,...,K) to each index i = 1...N     for i in range(len(labels)):         labels[i] = np.random.randint(0,K)             for iteration in range(iteration):          # Compute the centroid of cluster K         for k in range(K):             dp = X[np.where(labels == k)[0]]             centroids[k] = _________(1)___________                     # Assign observation n to the cluster with closest centroid         for n in range(N):             distance = np.linalg.norm(X[n]-centroids,axis=1)             labels[n] = _________(2)___________                 # Compute the distance between each data point and their centroids     within_cluster_distance = 0     for m in range(N):         within_cluster_distance += _________(3)___________             return within_cluster_distance     k_list = [] for i in range(1,10):     k_list.append(kmeans(X1,i,10))     x = np.arange(1,10) plt.plot(x,k_list) plt.xlabel('K') plt.ylabel('Within Cluster Distance') plt.show() The format of input $$X$$ is shown below: What should go in the third blank(3)?
