Gurth's Suggestions for Posting Solutions to Problems:

1. First try to understand what the problem-setter is trying to convey to you.

2. You are not there to nit-pick the way in which the problem has been set. If there is any point about which you are not clear, then do not resolve the doubt by making an arbitrary choice. Resolve it by asking a sensible question before you proceed.

3. You are definitely not expected to try to sabotage the problem, to make it appear silly or to imply that the rules are inadequate. If you think they are inadequate, then get that matter straightened out before you go further.

In the case of the House Number Problem, it is clear that the setter has constructed a puzzle that relies for its validity on the assumption that house numbers are integers. Fractional house numbers are at most in a freakish, tiny minority and to bring this fact into the discussion may be of interest, but it is of no interest to the solving of the problem. Because, if we allow fractional house numbers, then the problem is essentially DESTROYED, which is tactless to the well-meaning setter, in fact can only be seen as a boorish lack of a cooperative spirit. Please refrain from this type of one-up-manship. It is in no way funny or amusing.
