CF1691B Shoe Shuffling

洛谷题面 题目大意 求出每一个大小相同的“块”,如果有块的大小为 \(1\) 则无解。 否则,我们对于每个“块”,设组成此“块”的每个元素的下标为 \([i,i+1,\cdots,i+k]\),则答案排列为 \([i+k,i,i+1,\cdots,i+k-1]\)。 注意求无解和输出要分开操作。 代码 #include <iostream> #include

GoLang设计模式03 - 抽象工厂模式

之前我们介绍了工厂设计模式,现在我们再看一下抽象工厂设计模式。抽象工程模式顾名思义就是对工厂模式的一层抽象,也是创建型模式的一种,通常用来创建一组存在相关性的对象。 UML类图大致如下: 类图比较复杂,最好用个例子来说明。比方说,国内有两家生产运动服的工厂:nike和adidas 。现

《从零开始学python+自然语言处理100题》——给自己的记录

为了学习自然语言处理NLP,申请学校的老师给我发了100题,准备自己从零开始学python,记录一下。 https://nlp100.github.io/zh/ 00. 反转字符串 将字符串”stressed”中的字符以逆序形式(从末尾到首部)重组为新的字符串。    我选择了切片法:https://www.jianshu.com/p/15715d6f4dad

欧拉函数中的性质 Φ(p)=p-1,p为素数。所以这个题算是贪心+数论吧。每个Φ(p)=p-1;只要从p开始,找素数,那么一定有Φ(k)>=p-1;只有当p=k时,等号成立。 1 #include <iostream> 2 #include <cstring> 3 #include <string> 4 #include <map> 5 #include <set> 6 #include <algorithm>

题目描述:   题目大意:一个竹竿长度为p,它的score值就是比p长度小且与且与p互质的数字总数,比如9有1,2,4,5,7,8这六个数那它的score就是6。给你T组数据,每组n个学生,每个学生都有一个幸运数字,求出要求买n个竹子每个竹子的score都要大于或等于该学生的幸运数字,每个竹竿长度就是花费,求最小花费

spring事务详解(二)实例

在Spring中,事务有两种实现方式: 编程式事务管理: 编程式事务管理使用底层源码可实现更细粒度的事务控制。spring推荐使用TransactionTemplate,典型的模板模式。 申明式事务管理: 添加@Transactional注解,并定义传播机制+回滚策略。基于Spring AOP实现,本质是对方法前后进行拦截, 方法开始
