Then you've not seen worse xD

Where is myjinxin2015? I hope he is safe :)

This has to be the closest thing to a CTF on Codewars.

Okay it's language-specific. PHP has PCRE implemented.

Is it intentional that PCRE-style recursion using (?R) and (?<n>) is not supported?

Admin, is this an acceptable solution?

Such a simple solution needed to solve this kata. Overthinking got me finding another.

Test is giving the error below;

"Your regex should NOT match";

• 'aaaa c c ce e eeefffff ll pppppp '
• ' ccc eeee hhhhhh llloo t vvvv v yyyy y '
• ' hhhh xx xxyyy'

And more like that. Last I checked those are in alphabetical order with an arbitrary number of spaces at any index in the string.

Would fail for cycle(1, [1,2,3], 3) == 1

Absolutely no need giving an array as input. Integer n would suffice.

This assumes the elements are numbers.

FArekkusu's brain be like;

O(n) speed < O(n log n) : n <= 1

XD

This issue is not fixed.
