py.checkio.org, task.long-repeat-inside
PCRE2 (PHP >=7.3)
in this one you should find a repeating sequence inside the substring. I have an example for you: in a string "abababc" - "ab" is a sequence that repeats more than once, so the answer will be "ababab" `repeat_inside('aaaaa') == 'aaaaa' repeat_inside('aabbff') == 'aa' repeat_inside('aababcc'...
