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.

WebPerhaps because of this, the first algorithm for all-pairs shortest paths (in the 1960's) by Floyd based on Warshall's work took a dynamic programming approach. (We'll get to that later.) But then Johnson had a bright idea in 1977 that salvaged the greedy approach. WebFloyd-Warshall All-Pairs Shortest Path. Directed Graph. Undirected Graph. Small Graph. Large Graph.
