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…

#include <stdio.h>#include <string.h> int main(){    int T, k, len;    char str[81], *p, *q, *end;    scanf("%d", &T);    while (T--)    {        scanf("%s", str);        len = strlen(str);        end = str+len;        …

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…

一:这种结论,个人觉得仍然存疑 http://www.cnblogs.com/wangshuai901/archive/2012/05/06/2485657.html 1.null    null 关键字是表示不引用任何对象的空引用的文字值.null 是引用类型变量的默认值.那么也只有引用型的变量可以为NULL,如果 int i=null,的话,是不可以的,因为Int是值类型的. 2.,""和String.Empty    这两个都是表示空字符串.只不过""理论上重…
