Web1 day ago · JavaScript Program for Range sum queries for anticlockwise rotations of Array by K indices - Anticlockwise rotation of an array means rotating all the elements of the given array to their left side by the given number of indexes. In this article, we will implement a JavaScript program for range sum queries for anticlockwise rotations of the array by k … WebK-means clustering algorithm computes the centroids and iterates until we it finds optimal centroid. It assumes that the number of clusters are already known. It is also called flat clustering algorithm. The number of clusters identified from data by algorithm is represented by ‘K’ in K-means.
