志雄正潜心研究24点算法，向我要全排列的算法，我给他一个利用堆栈解决方法，寥寥几行，志雄叫好。看他挺专心的，于是我也加入他的24点项目。花了一个晚上考虑算法，第二天早上，完全实现了我的算法，用时0.75秒，解出1900道24

最长公共子串和最长公共子序列。。。傻傻烦不清楚   举个栗子： str1="123ABCD456"  str2 = "ABE12345D" 最长公共子串是：123 最长公共子序列是：12345   这两个都可以用动态规划，只是状态转移方程有点区别   最长公共子序列是： dp[i][j] -- 表示子串str1[0...i]和子串str[0...j]的最长公共子序列 当str1[i] == str2[j]时，dp[i][j] = dp[i-1][j-1] + 1; 否则，dp[i][j] = max(dp[i-1][j], dp[i][j-1]); 最优解为dp[len1-1][len2-1];   最长公共子串是： dp[i][j] -- 表示以str1[i]和str2[j]为结尾的最长公共子串 当str1[i] == str2[j]时，dp[i][j] = dp[i-1][j-1] + 1; 否则，dp[i][j] = 0; 最优解为max(dp[i][j]),其中0

一、随机点名系统需求分析 1、引言 在高等院校、职中专、大专学校里，学生考勤是一项日常必要性的工作，学校的各院系需要了解和掌握各班级的学生出勤情况，以加强对学生的教育和管理。因而学生考勤是学校一项非常重要的工作。 传统的学生考勤以及平时在课堂上的表现，主要是依靠老师在课堂上点名或学生会抽查点名制度，还有上课提问等。学生人数多、考勤不全面、数据不准确，特别是点名考勤制耗费了老师和学生大量的时间且起不到太大的效果。 (A random name system requirements analysis 1 Introduction In higher education, post secondary, tertiary school, student attendance is a necessity of daily work, school faculties need to understand and master students in each class attendance, to enhance the student' s education and management. Thus student attendance is a very important school work. The traditional student attendance and performance in the classroom usually, mainly relying on the teacher or the student named in the classroom random name system, as well as class questions, etc. Number of pupils, attendance is not comprehensive, the data is not accurate, especially upon attendance system, teachers and students spent a lot of time and not be of much effect.)
