Kolya got string s for his birthday, the string consists of small English letters. He immediately added k more characters to the right of the string. Then Borya came and said that the new string contained a tandem repeat of length l as a substring. H…

题目链接:http://codeforces.com/contest/443/problem/B 题目意思:给出一个只有小写字母的字符串s(假设长度为len),在其后可以添加 k 个长度的字符,形成一个长度为len+k的新串 s'.问在 s' 中,可以形成的最长tandem repeat 是 多长.tandem repeat 的定义是:si = si+n (1 <= i <= n; 2*n <= k+len) 注意,这个tandem repeat 是相邻的!!也就是对于abcwerabc…

本题要考虑字符串本身就存在tandem, 如测试用例 aaaaaaaaabbb 3 输出结果应该是8而不是6,因为字符串本身的tanderm时最长的 故要考虑字符串本身的最大的tanderm和添加k个字符后最大的tanderm #include <iostream> #include <vector> #include <algorithm> #include <string> #include <set> using namespace std…

题意:给出一个字符串,给出k,可以向该字符串尾部添加k个字符串,求最长的连续重复两次的子串 没有想出来= =不知道最后添加的那k个字符应该怎么处理 后来看了题解,可以先把这k个字符填成'*',再暴力枚举起点和长度,找出最大的长度 #include<iostream> #include<cstdio> #include<cstring> #include <cmath> #include<stack> #include<vector>…

一.repeat语句格式repeat语句用于"重复执行循环体,直到指定的条件为真时为止" repeat语句格式:repeat  语句1;  语句2;  --  语句n;until 布尔表达式; repeat重复基本上有与while重复一样的描述循环计算的能力,但有三点不同:1.在repeat语句中,布尔表达式求值在循环体执行之后,而在while语句中,布尔表达式求值在循环体执行之前.2.while语句的循环体部分只能是一个语句,因此当重复动作包含几个语句时,需用begin和end使它们…

DRY是指Don't Repeat Yourself特指在程序设计以及计算中避免重复代码,因为这样会降低灵活性.简洁性,并且可能导致代码之间的矛盾.<The Pragmatic Programmer>对这一思想做了很好的阐述. 把一切重复的代码抽象出来.我觉得最主要的原因是很好维护,当需要改动时只需要改动一次. 代码复用的层次:函数级别复用,对象级别复用,接口级别的,类库级别复用,框架级别复用.注:我们目前还处在“函数级别复用”上.(这个最基本的做好也减少了不少重复代码.....) 另一个有关…

Operator repeat() is somewhat similar to retry(), but is not for handling operators. In this lesson we learn how repeat works. var foo = Rx.Observable.interval(500) .zip(Rx.Observable.of('a','b','c','d'), (x,y)=>y); var bar = foo.map(x => x.toUpperC…
