hdoj 1002 A+B(2)

Problem Description I have a very simple problem for you. Given two integers A and B, your job is to calculate the Sum of A + B. Input The first line of the input contains an integer T(1<=T<=20) which means the number of test cases. Then T lines f…

ACM中Java的应用

先说一下Java对于ACM的一些优点吧: (1) 对于熟悉C/C++的程序员来说Java 并不难学,两周时间基本可以搞定一般的编程,再用些时间了解一下Java库就行了.Java的语法和C++非常类似,可以说是C++的升级版,只是更加强调面向对象思想而已.(个人见解...) (2) 在一般比赛中,Java程序会有额外的时间和空间,但真正进行大规模运算时Java并不比C/C++慢,输入输出效率比较低而已 (3) Java 代码简单且功能强大,有些像高精度之类的算法用Java实现起来更为简洁方便(AC…

DFS ZOJ 1002/HDOJ 1045 Fire Net

题目传送门 /* 题意:在一个矩阵里放炮台,满足行列最多只有一个炮台,除非有墙(X)相隔,问最多能放多少个炮台搜索(DFS):数据小,4 * 4可以用DFS,从(0,0)开始出发,往(n-1,n-1)左下角走,x = cnt / n; y = cnt % n; 更新坐标, 直到所有点走完为止,因为从左边走到右边,只要判断当前点左上方是否满足条件就可以了注意:当前点不能放炮台的情况也要考虑 g[x][y] == 'o'; 的错误半天才检查出来:) */ #include <cstdio> #…

【2017多校训练08 1002】【HDOJ 6134】Battlestation Operational

典型的数列反演题. 运用莫比乌斯反演的一个结论 $[n = 1] = \sum_{d | n} \mu(d)$,将表达式做如下转化: $$ ans = \sum_{i=1}^n \sum_{j=1}^i (\lfloor \frac{i-1}{j} \rfloor + 1) \sum_{d | i \land d | j} \mu(d) \\ = \sum_{d=1}^n \mu(d) \sum_{i=1}^{\lfloor \frac{n}{d} \rfloor} \sum_{j=1}^i (…
