Andre, By "upside-down" I mean the rotation of the (vertical) plane by 180 degrees around a (horizontal) line perpendicular to the plane. :) Leo On Sun, Sep 22, 2019 at 4:45 PM Andres Valloud < avalloud@smalltalk.comcastbiz.net> wrote:
Hi Leo, could you please clarify for me what you mean when you say 'upside-down'?

Out of two strings matching [0125689]{5}, where the second string corresponds to the upside-down reading of the first, no more than one string will be a valid zip code.

Regarding the subject, it appears US (basic) zip codes are effectively character digit strings of length 5 (that is, [0-9]{5}). Some state there are 42k active zip codes, presumably of the five digit variety.

So you really meant to map 0125689 to 0152986? On 10/3/19 9:08 , Leo Broukhis wrote:
