Puzzles/POY 2005
Puzzle of the year 2005: find phrases that generate each number i.100 , making no use of
- digits other than 2 0 0 5 in sequence
- _ and __ and _. as numbers
- letters in numeric constants (e.g. 200r5 for 40 is prohibited)
- literal strings
The number of words in each phrase is to be minimized. (Word count is according to #;:y ). Where there are multiple phrases for the same number with the same number of words, phrases with fewer essential characters are preferred.
<!> Note: This page is a community effort, and one objective is to have an "interesting" puzzle. If you discover loopholes in the current rules that make the puzzle completely uninteresting, a better contribution would be to tighten the rules, rather than to fill up the page with uninteresting entries exploiting the loopholes. For example, if _ and __ as numbers were permitted, then # 2005 _ and # 2005 _ _ etc. would pretty well solve the whole thing. Now what fun would that be?
