課程設計：
1.求出在一個n×n的棋盤上，放置n個不能互相捕捉的國際象棋“皇后”的所有布局。
2.設計一個利用哈夫曼算法的編碼和譯碼系統，重復地顯示并處理以下項目，直到選擇退出為止。
【基本要求】
1) 將權值數據存放在數據文件(文件名為data.txt，位于執行程序的當前目錄中)
2) 分別采用動態和靜態存儲結構
3) 初始化：鍵盤輸入字符集大小n、n個字符和n個權值，建立哈夫曼樹；
4) 編碼：利用建好的哈夫曼樹生成哈夫曼編碼；
5) 輸出編碼；
6) 設字符集及頻度如下表：
字符 空格 A B C D E F G H I J K L M
頻度 186 64 13 22 32 103 21 15 47 57 1 5 32 20
字符 N O P Q R S T U V W X Y Z
頻度 57 63 15 1 48 51 80 23 8 18 1 16 1
SensorSimII is the framework of a simulator that I have been working on to study how future sensor networks should operate. the simulator is written in a modular fashion so that it can be adapted to serve a number of needs. However, please remember that it is still a work in progress. This web page is here just to give a glimpse of the approach we ve taken with this simulator. Likewise this web page is simply preliminary information to attempt to answer some of the questions that researchers might have about this project.
