WebAnother example for my students learning Huffman coding. In this video I show you how to build a Huffman tree to code and decode text. WebThe Greedy method is the simplest and straightforward approach. It is not an algorithm, but it is a technique. The main function of this approach is that the decision is taken on the basis of the currently available information. Whatever the current information is present, the decision is made without worrying about the effect of the current ...
