詞法分析 1 試驗目的 設計,編制并調試一個此法分析程序,加深對此法分原理的理解. 2 試驗要求 1)待分析的簡單語言的詞法 * 關鍵字: begin if then while do end 所有關鍵字都是小寫. 2)運算符和界符: : = + * - / < <= <> > >= = ( ) # 3)其他單詞是標識符(ID)和整數型常數(NUM),通過一下正規式定義: ID=letter (letter|digit)* NUM=digit digit* 4)空格由空白,制表符和換行符組成,空格一般用來分隔ID,NUM,運算符,界符和關鍵字,此法分析階段通常被忽略. 3 各種單詞符號對應的種別碼如表所示

Huffman codes In telecommunication, how do we represent a set of messages, each with an access frequency, by a sequence of 0’s and 1’s? To minimize the transmission and decoding costs, we may use short strings to represent more frequently used messages. This problem can by solved by using an extended binary tree which is used in the 2- way merging problem.
