| Sep 7, 2020 at 15:29 | comment | added | Iosif Pinelis | @ErelSegal-Halevi : You did say "if such x exists". The bulk of the work here was to formalize the problem. Anyway, I think that without the existence assumption and with a reasonable formal interpretation, the answer will change to "no". However, I'd suggest that you post, separately, a quite formally presented question without the existence assumption, avoiding such terms as "query", "access", etc. or perhaps using them only for an accompanying informal version of the question. | |
