Question

I am in need of a regfex for a validation framework which accepts regex formats for validation.
I cannot use arithmetic and comparative operators. I have come up with a solution but It is not working as expected.
I want to know what’s wrong with the regex which I came up with and how to sort it out right

Regex for any number from 10429 to 40999

My solution:

^1042[9-9]|104[3-9][0-9]|10[5-9][0-9][0-9]|1[1-9][0-9][0-9][0-9][0-9]|[2-3][0-9][0-9][0-9][0-9]|40[0-9][0-9][0-9]

But this one is not working.

Answer 1

Try this

^(10429|104[3-9][0-9]|10[5-9][0-9]{2}|1[1-9][0-9]{3}|[23][0-9]{4}|40[0-9]{3})$
