How do I modify the following regex to match on the first occurrence of a digit in a year (e.g. 2020)?

I have the following regex expression but it fails to match on only the 1st occurrence of the digit "2":

(?<=[a-zA-Z0-9])[2A-Z]

For example, if I use the string "fifa2020" it will match on both 2's. I only want it to match on the first 2.

How do I modify the existing regex (I need the parts of it that are currently working) to achieve what I want?

It depends on the language, but you can remove the global flag https://regex101.com/r/aRuJDx/1 – The fourth bird Aug 03 '22 at 20:48
Using groups: `^(.*?[a-zA-Z0-9])?([2A-Z].*)` – Wiktor Stribiżew Aug 03 '22 at 20:50
It can easily happen that your programming language has a method to catch the first match only. – lemon Aug 03 '22 at 20:51
anyone know the best way to do this in kotlin? I think kotlin defaults to global – d2learner Aug 03 '22 at 20:59
Maybe using find https://kotlinlang.org/api/latest/jvm/stdlib/kotlin.text/-regex/find.html – The fourth bird Aug 03 '22 at 21:10
