這是一個考試系統，主要實現的題目有單項選擇題，多項選擇題和判斷題。 1.對于每個題都是每次運行本軟件的時候自動從題庫中隨機抽取。 2.在data文件夾下有一個配制文件： a.它可以修改每個類型的題目的數量。 b.它可以修改第個題目的分值。 c.它可以修改考試的限定時間。 3.在交卷后就可以查看，本次考試的得分。并根據本次考試滿分的60％做為標準，來判斷你是否通過這次考試。 4.后臺是一個Access數據庫，就可以加入新的題目。并不需要修改原程序。 判斷題的表是judge,單選是single,多選是moresingle表， 5.在Access中可以添加新的考試人員。只要添加student表中的信息就可以了。 6.在每次交卷后的成績，會重新保存到數據庫中。 7.每次交卷后，都可以把這次所做的題目導出，包括答案和學生所做的答案，以及這次考試的得分。 8.在沒有交卷前，做完的題目可以再次進行修改。 9.顯示現在時間 吉林農業科技學院 06計算機科學與技術一班 幽居古藤

Compression using lempel-ziv -for a dictionary size of 2k -provide dictionary Lempel ziv algorithm is a dictionary based algorithm that addresses byte sequences from former contents instead of the original data. This algorithm consists of a rule for parsing strings of symbols from a finite alphabet into substrings, whose lengths do not exceed a prescribed integer and a coding scheme which maps these substrings sequentially into uniquely decipherable code words of fixed length. The strings are selected so that they have nearly equal probability of occurrence. Frequently-occurring symbols are grouped into longer strings while occasional symbols appear in short strings.
