WebMar 24, 2024 · Kruskal algorithm is a minimum spanning tree algorithm in which in every iteration, minimum weighted edge is found and then it is added to the construction of minimum spanning tree. Edges are added in increasing order of the edge weights. That’s why it is a greedy approach. Floyd Warshall algorithm is based on the principle of … WebHuffman Coding is a famous Greedy Algorithm. It is used for the lossless compression of data. It uses variable length encoding. It assigns variable length code to all the characters. The code length of a character depends on how frequently it occurs in the given text. The character which occurs most frequently gets the smallest code.
