暴力枚举下就行了，没有算法。。不过要细心点。。我开始的时候那while循环逻辑写错了，卡了半天，去找了测试数据才知道错哪了。。还是逻辑不够严密

#include<stdio.h>
#include<string.h>

int main()
{
    char s[41];
    while (gets(s), strcmp(s, "END") != 0)
    {
        int len = strlen(s);
        int ip, d;
        int maxcount = -1, maxlen = -1, maxip = -1, mind = 0xFFFFFFF;
        for (ip = 0; ip < len; ip++)
        {
            for (d = 1; d <= len - ip; d++)
            {
                int count = 0, length = ip;
                while (s[length] == '.')
                {
                    length += d;
                    count++;
                    if (length >= len)
                    {
                        length -= d;
                        break;
