Periodic Strings

Description

 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 repetitions of the string "abc". It also has periods 6 (two repetitions of "abcabc") and 12 (one repetition of "abcabcabcabc").

Write a program to read a character string and determine its smallest period.

Input

The first line oif the input file will contain a single integer N indicating how many test case that your program will test followed by a blank line. Each test case will contain a single character string of up to 80 non-blank characters. Two consecutive input will separated by a blank line.

Output

An integer denoting the smallest period of the input string for each input. Two consecutive output are separated by a blank line.

Sample Input

Sample Output

思路：字符串长度不超过80，可以采用暴力枚举的方法，枚举出他的周期。判断相邻周期内的字符是否相等，如果满足，先break跳出，判断字符长度是否是周期的倍数。

# include <stdio.h>          # include <string.h>int main(){    char a[100];    int i, n, j, L, f, len, cnt=0, k;    scanf("%d",&n);    getchar();    k=n;    while(n--)    {        scanf("\n");        gets(a);        cnt++;        len = strlen(a);        for(i=1; i<=len; i++)        {            f=1;            for(j=0; j+i<len; j++)            {                if(a[j]!=a[j+i])                {                    f=0;                    break;                }            }            if(f==1&&len%i==0)            {                L=i;                break;            }        }        printf("%d\n",L);        if(cnt!=k)            puts("");    }    return 0;}
