matching all 5 digits numbers other than 3 specific ones-without negative lookbehind

Question

So I am trying to match with any 5 digits number other than 10000,11000,68000. With negative lookbehind, lookaround etc. this code does exactly what I want

^[0-9]{5}(?<!10000|11000|68000)$

.However, I would like to do it without using lookbehind. Is there any nice way to do it?

Thank you!

Answer 1

This will match all 5 digit numbers excluding your few listed
excludes numbers 10000, 11000, and 68000

The ranges are:

00000 - 09999
10001 - 10999
11001 - 67999
68001 - 99999

^(?:0\d{4}|(?:1000[1-9]|100[1-9]\d|10[1-9]\d{2})|(?:1100[1-9]|110[1-9]\d|11[1-9]\d{2}|1[2-9]\d{3}|[2-5]\d{4}|6[0-7]\d{3})|(?:6800[1-9]|680[1-9]\d|68[1-9]\d{2}|69\d{3}|[7-9]\d{4}))$
