repeating multiple characters regex

Question

Is there a way using a regex to match a repeating set of characters? For example:

ABCABCABCABCABC

ABC{5}

I know that\'s wro

Answer 1

ABC{5} matches ABCCCCC. To match 5 ABC's, you should use (ABC){5}. Parentheses are used to group a set of characters. You can also set an interval for occurrences like (ABC){3,5} which matches ABCABCABC, ABCABCABCABC, and ABCABCABCABCABC.

(ABC){1,} means 1 or more repetition which is exactly the same as (ABC)+.

(ABC){0,} means 0 or more repetition which is exactly the same as (ABC)*.
