fixed for Java

(see recent java fork)

This is an 8kyu kata, enforcement of regex is not only inappropriate with the level of ranking, but also too late as it will invalidate all solutions

Seems to be fixed to this day

Done some time ago

hahaha ur mad communist kiddo

It's not a kata issue, it's a problem with your code.

It's called the Spread Syntax, here is the official documentation for it.

Confirmed. That's Java.

(Note: For an unknown reason, I don't see the "edit kata" button while the issue is open... :o )

You use the first element as the initial value and then fold XOR across all other values.

sure suggestions are welcome

You know what it is, I probably meant to write 31 since the test cases are all integers. Still a dumb solution.

I made a new fork with a more explicit solution, apologies for the issue.
