Huffman coding greedy algorithm
Web8 sep. 2024 · Huffman Coding The algorithm was developed by David A. Huffman in the late 19th century as part of his research into computer programming and is commonly found in programming languages such as C, C + +, Java, JavaScript, Python, Ruby, and more. WebCode前要先做出graph，再寫出Prim’s AL找出MST. Repl. Kruskal’s Algorithm. 也是找出MST的演算法，與Prim’s algorithm同樣被歸類為”Greedy Algorithm” 列出所有edges; 從weight最小的開始，排除會形成loop的edge，放入MST edge list中; 會得到相同的MST。時間複雜度O(n logn) Application of MST
