如果一个字符串可以被某个长度为k的字符串重复多次得到,则称这个字符串的周期为k.例如,字符串"abcabcabcabc"以3为周期(当然,他也以6.12等等为周期).  现在请你编写一个程序,求出任一长度不超过80的字符串的最小周期. Input 输入首先是一个整数n,代表有n组数据. 每组数据占一行,是一个长度不超过80的字符串. 两组相邻的输入之间有一个空行. Output 每组数据在一行内输出一个整数k,代表该字符串的最小周期. 两组相邻的输出之间应当有一个空行. Sample…

UVa OJ 455 Periodic Strings A character string is said to have period k if it can be formed by concatenating one or more repetitions of another string of length k. For example, the string "abcabcabcabc" has period 3, since it is formed by 4 repe…

解题思路: 对一个字符串求其最小周期长度,那么,最小周期长度必定是字符串长度的约数,即最小周期长度必定能被字符串长度整除 其次,对于最小周期字符串,每位都能对应其后周期字串的每一位, 即 ABC  ABCABC (345678)->%其字串长度3 012  3%3 4%3 5%3  6%3 7%3  8%3   0      1     2        0      1       2 if(a[j]!=a[j%3])说明不对应,不是周期,进行下一位扫描. AC Code: #include<…

题目的意思是一个字符串有某个长度为k的字符串通过不断重复形成的,而k被称为该字符串的周期.而我们所要做的是找出该字符串的最小周期. input The first line is an integer T,That means there are have T test cases; the following T lines are T strings; output Each line is an answer,and there a blank line between two answe…

1.题目大意 求一个长度不超过80的字符串的最小周期. 2.思路 非常简单,基本就是根据周期的定义做出来的,几乎不需要过脑. 3.应该注意的地方 (1) 最后输出的方式要注意,不然很容易就PE了.不过个人认为,其实这题Sample Output给的不好 (2) 注意输出的要求是最小周期 4.代码 #include"stdio.h" #include"string.h" #define maxn 80 int main() { int T,m,i,j,flag; ch…

首先先讲一下KMP算法作用: KMP就是来求在给出的一串字符(我们把它放在str字符数组里面)中求另外一个比str数组短的字符数组(我们叫它为ptr)在str中的出现位置或者是次数 这个出现的次数是可以重叠的 例如:在数组   ababa    中  aba的出现次数-----------它的答案是2------分别是从[0---2]  [2---4] 他们是可以重叠的,但是不可以完全重叠(废话T_T) KMP算法主要有两个模板 1.https://blog.csdn.net/starstar1…

使用strings查看二进制文件中的字符串 今天介绍的这个小工具叫做strings,它实现功能很简单,就是找出文件内容中的可打印字符串.所谓可打印字符串的涵义是,它的组成部分都是可打印字符,并且以null或者newline结尾. 对于普通文本文件来说,strings没有任何意义,因为文本文件中的任何内容实际都是可打印的字符串.strings最常用的场合就是列出动态库或者可执行程序等二进制文件中出现的字符串,结合grep即可实现查找. strings的使用方法很简单,strings [文件]即可,…
