传送门 题意:从输入开始,1.输入样例数:2.然后输入一组样例中的行数n:3.前n-1行为定义变量(之间使用空格隔开),只需要map存进去就可以了(这里有覆盖的情况,故使用mp["s"] = "***"的方法赋值,因为insert的方法如果里面存在的话,插不进入数值):4.然后就是最后一行输入计算式子(之间使用空格隔开). 思路:我使用的字符流的方法分割的的字符串,因为题中说了使用空格隔开的: 变量的储存使用map就可以,在最后一行输入计算式子之后,同样使用字符流分…

第一眼看到这题就直接BFS爆搜,第一发爆了内存,傻逼了忘标记了,然后就改,咋标记呢. 然后想到用map函数,就8!个不同的排列,换成字符串用map标记.然后又交一发果断超时,伤心,最恨超时,还不如来个wa算了. 然后卡着了,后来上网上搜,要用康托展开,康托展开是什么鬼?然后学习了一下,就是个映射,感觉和map差不多. http://blog.csdn.net/zhongkeli/article/details/6966805这个学习一下康托展开. 其实本题的关键不是康托展开,而是置换. 以123…

解题报告:有一群人在打乒乓球比赛,需要在这一群人里面选出一个冠军,现在规定,若a赢了b,b又赢了c那么如果a与c没有比赛的话,就默认a赢了c,而如果c赢了a的话,则这三个人里面选不出冠军,还有就是如果一个人没有输给别人,但是存在一个人跟这个人之间的输赢关系不能确定的话,也是作为选不出冠军的情况,现在输入一群人的比赛情况,要你确定,利用这组比赛情况能不能确定一个冠军,能的话输出Yes,否则输出No. 感觉这题应该有很多种不同的解法,其中由于输入的是选手的名字,所以还要用到map容器.我的做法是枚举…

SpringBoot 也算AI吧,它根据您架构中引用的依赖,自动化地按默认方案帮您完成了Spring那些复杂繁琐的配置工作.为了让您不会看低此 AI 水平,还特地喊出了“约定大于配置”的口号.从这个角度看,SpringBoot 就是基础架构搭建工具,与系统业务逻辑实现没什么关系,这和Maven有点类似. 既然是搭建,SpringBoot 当然推荐 Maven 或 Gradle.另外,SpringBoot 要求 JDK1.8+ 环境. SpringBoot 提供一系列基于spring-boot-s…
