詞法分析器制作與應用 設計思想 (1)程序主體結構部分: 說明部分 %% 規則部分 %% 輔助程序部分 (2)主體結構的說明 在這里說明部分告訴我們使用的letter,DIGIT, IDENT(標識符,通常定義為字母開頭的字母數字串)和STR(字符串常量,通常定義為雙引號括起來的一串字符)是什么意思.這部分也可以包含一些初始化代碼.例如用#include來使用標準的頭文件和前向說明(forward ,references).這些代碼應該再標記"%{"和"%}"之間 規則部分> 可以包括任何你想用來分析的代碼 我們這里包括了忽略所有注釋中字符的功能,傳送ID名稱和字符串常量內容到主調函數和main函數的功能. (3)實現原理 程序中先判斷這個句語句中每個單元為關鍵字、常數、運算符、界符,對與不同的單詞符號給出不同編碼形式的編碼,用以區分之。 PL/0語言的EBNF表示 <常量定義>::=<標識符>=<無符號整數> <標識符>::=<字母>={<字母>|<數字>} <加法運算符>::=+|- <乘法運算符>::=*|/ <關系運算符>::==|#|<|<=|>|>= <字母>::=a|b|…|X|Y|Z <數字>::=0|1|2|…|8|9

In this letter, the error performance of an ultra-wideband (UWB) system with a hybrid pulse amplitude and position modulation (PAPM) scheme over indoor lognormal fading channels is analyzed. In the PAPM UWB system, input data is modulated onto both the pulse amplitudes and pulse positions.

北京大學ACM比賽題 The game of Scrabble is played with tiles. A tile either has a single letter written on it, or it is blank. In the latter case, the tile may be used to represent a letter of your choice. On your turn, you arrange the tiles to form a word. Each tile may be used at most once, but not all tiles need to be used. Given several Scrabble tiles and a dictionary, determine how many words in the dictionary can be formed using the given Scrabble tiles.

北京大學ACM比賽題目 In 1742, Christian Goldbach, a German amateur mathematician, sent a letter to Leonhard Euler in which he made the following conjecture: Every even number greater than 4 can be written as the sum of two odd prime numbers. For example: 8 = 3 + 5. Both 3 and 5 are odd prime numbers. 20 = 3 + 17 = 7 + 13. 42 = 5 + 37 = 11 + 31 = 13 + 29 = 19 + 23. Today it is still unproven whether the conjecture is right. (Oh wait, I have the proof of course, but it is too long to write it on the margin of this page.) Anyway, your task is now to verify Goldbach s conjecture for all even numbers less than a million.
