Awesome! Actually I had a hard time to understand what I need to do first few seconds.

Ruby translation, please check and approve :-)

OK, that should do it.

Made a small improvement on the random tests

Needs better random tests.

This solution shows why you should calculate expected before actual, and/or give the user ( and possibly the reference solution as well ) a copy of the random input argument.

The above does not apply to primitives, but it does apply to all objects, including but not limited to arrays.

As mentioned below, please await confirmation ( for a reasonable amount of time ) before closing this issue. I might know more ways to break your random tests; getting random testing right may be an iterative process.

I have reopened the issue because your random test is not done correctly.

Please keep issues open for a little while until you have confirmation the issue has actually been solved.

If possible please check the random test case is resolved so i can ensure it is done correctly.

I have just added a random test case. If you would be able to confirm this is done correctly I would appricitate feedback.

I have now added a random test case, please would you check if this is done correctly so i can make any improvements.

Oh I see haha

Already mentioned twice before.

No random tests

Same issue. No random tests

Needs random tests ..
