Regex capture all matches in word

Question

For example, I have this string:

222

What pattern I should use to get a count of "22" matches exactly 2 times?

222 -> (22)2 and 2(22)

So, for 2222 I would have 3 matches:

2222 -> (22)22 and 2(22)2 and 22(22)

Answer 1

You can use Positive Lookahead:

2(?=2)

Answer 2

Try 2{2}. The number inside the braces is the number of repetitions of the token prior to the opening brace.
