    scanf("%d",&times);
    for( i=0;i<times;i++)
    { 
         char p[1000000];   
        int j=0,longest=0,result=0;

        scanf("%s",p);
    //  printf("%s\n",p);
    //  printf("strlen%d\n",strlen(p));
    //  while(p[j]!='\0')



       for(j=0;j<strlen(p);j++)
        {

            if(p[j]=='.')
            {sum=0;
                for( k=j;p[k]!='#';k++)
