You have a question in the format "No A is within a class B". The algorithm for such problem is

bool wrong = false;
while ( /* there is another A */ )
{
   if ( /* check if it is NOT within a class */ )
   {
      wrong=true;
      break;
   }
}
if (wrong)
{
  // here you know that at least one thing was NOT within a class B
}
else
{
  // here you know that every item A was within a class B
}

In your case the "class" is "Strings with no space" and to check if there is space you just use this condition.
