What regex pattern would work here?

Question

Regular Expressions

Greetings.
Regex.Replace(links[i],"\\?p=[\\d]{1,}\\?p","?p");
Captures ?p=1?p=2
AND turns it into ?p=2.
Please tell me how to adapt to this situation.
It was

?size=30&lang=ru&first=579&start=539?size=30&lang=ru&first=579&start=501

It became That
?size=30&lang=ru&first=579&start=501
is to remove the double
?size=30&lang=ru&first=579&start=539
Thank you very much.

Answer 1

perhaps this option
or another option
but here you need to test on sharp (or whatever you have) :)
