我刷的很少，只有这么点

万能头 #include<bits/stdc++.h> 这60%会造成TLE 包含了algorithm、cmath…… （会超时） 简单题目不会 题目TLE 未优化 使用contitune 检查方式 （这个是你的输入手速） 看这个 一般只有1s的时间 请你用检查超时

1.WA（样例错误） 2.AC（样例正确） 3.MLE（超出内存限制） 4.OLE（输出超时、输出过大） 5.TLE（运行超时） 6.PE（输出格式错误） （一般就是缺少空格、换行） 7.RE（运行错误） 8.SE（系统错误） 彩虹题

动规(Dynamic Programming)类问题主要求解的步骤: 斐波那契数列\color{Blue}{斐波那契数列}斐波那契数列 1. 划分阶段 斐波那契数列的每一项作为一个阶段\color{Blue}{斐波那契数列的每一项作为一个阶段}斐波那契数列的每一项作为一个阶段 2. 确定状态 第i项的值用数组第i位表示:ai\color{Blue}{第i项的值用数组第i位表示:a_i}第i项的值用数组第i位表示:ai 3. 确定答案所在位置 an\color{Blue}{a_n}an 4. 确定决策并写出状态转移方程式 ai=ai−1+ai−2\color{Blue}{a_i = a_{i-1}+a_{i-2}}ai =ai−1 +ai−2 5. 初始化 a1=a2=1\color{Blue}{a_1 = a_2 = 1}a1 =a2 =1

本体题解非常简单： #include<bits/stdc++.h> using namespace std; int main(){ int k,n=2; double s=1.0; cin>>k; while(s<=k){ s+=1.0/n; n+=1; } cout<<n-1; return 0; } 禁止抄袭

集训营10天速通C++语法! 我们的赞助商： 注意，抽象部分想它的谐音，因为不让发（可能会找来老师的注意） ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------ > DAY1 早上9点上课，复习C++，课间眼保健操，中午吃KFC，还有下午茶，模拟考，吃米村，分析错题，回家 > DAY2 还是上早8，但是没有烟包剪草，中午吃了国朝外卖（你没听错，我晕碳了）我们老师说下午户外活动不乱跑就喝可乐，下午茶吃蒟蒻和水果，户外活动之后就模拟考，晚上吃南城香，（最后一天吃M）之后就分析错题‘ > DAY3 还是没有眼保健操，中午还是南城香，下午茶增加了饼干，模拟考之后吃饺子本来说可能吃老乡鸡，没有户外活动但有游戏 > DAY4 没有烟草，中午吃了必胜客，晚上用乐高做了一个紫菜按摩机器 > DAY5 没有烟草，按摩机器傻乐人，本来吃烤肉但改成饺子了，因为预算不够。 > DAY6 这一天讲的全是数学，我数学不好所以.......中午吃的眉州东坡，腊肉给的很少，晚上还是南城香，没有烟草，但晚饭时同学说要消灭AC君，07，大黄，但之后他被紫菜了 > DAY7 讲的函数,模拟赛出的题很少，但是我忘了string反转函数（声音逐渐变小）中午煲仔饭，晚上馄饨生煎包。（互动 | 如果同时进入复仇者联盟和天之神会发生什么？） > DAY8 讲的是sort，模拟赛很容易AK（除T6T7）中午麦当当（提前2天）晚上牛肉面 > DAY9 讲了结构体，晚上煲仔饭好像吃出了问题 > DAY10 老师从一开始就一直说要将二维数组，最后一天才讲。最后总复习，中午吃披萨（必胜客）结营仪式有蛋糕 另外，我们把丁老师的全勤机器“修理”了一遍，别告诉他我们把他唯一红卡藏在全勤转轴下面 声明一下，如果有人（北京亚运村学员）找到一教的全勤机器（上面写了“全勤”，被丁老师贴满了小马宝莉贴纸）下面的宝可梦红卡，请放回去。谢谢 > THE END > 番外
