Same problem for me with PHP

Thansk for agreeing that I'm correct! I thought I was going mad. I'm not sure (I'm in training and have a lot to still learn about Ruby). However, I dind't modify any of the inputs for the random tests.

It would seem you are correct.

Does Ruby allow input modification? The translation seems vulnerable to that. Are you modifying your inputs?

( I don't know Ruby, so I'm poking in the dark a bit. )

I am attempting this kata in Ruby and passed all the test cases. However, in the random tests, if the input array has 3 + 0s in it I am failing.

When I check the expected compared to my solution, the expected seems to have always deleted the 3rd & 4th 0 of the input array, but surely it should only be deleting the 4th as that's the second 0 in the pair. Surely only every other occourance should be deleted? I can see people have passed the test on Ruby so am I just missing something here? Some examples below:

Examples:
[5, 4, 3, 7, 4, 3, 2, 9, 2, 9, 7, 1, 2, 8, 0, 0, 3, 2, 7, 4, 5, 4, 9, 0, 4, 0, 5, 2, 5, 5, 4, 0, 2, 3, 5, 4, 6, 2, 5, 4, 9] input
[5, 4, 3, 7, 4, 3, 2, 9, 2, 9, 7, 1, 2, 8, 0, 3, 2, 7, 4, 5, 4, 9, 4, 5, 2, 5, 5, 4, 0, 2, 3, 5, 4, 6, 2, 5, 4, 9] expected
[5, 4, 3, 7, 4, 3, 2, 9, 2, 9, 7, 1, 2, 8, 0, 3, 2, 7, 4, 5, 4, 9, 0, 4, 5, 2, 5, 5, 4, 0, 2, 3, 5, 4, 6, 2, 5, 4, 9] my result

[6, 3, 9, 2, 9, 0, 7, 7, 5, 4, 9, 1, 7, 6, 4, 5, 0, 6, 0, 9, 6, 6, 3, 9, 0, 2, 4, 5, 7, 3, 8, 1, 2, 9, 4, 7, 4, 0, 0, 6, 5, 4, 4, 4, 4, 2, 7, 8, 6, 1] input
[6, 3, 9, 2, 9, 0, 7, 7, 5, 4, 9, 1, 7, 6, 4, 5, 6, 9, 6, 6, 3, 9, 2, 4, 5, 7, 3, 8, 1, 2, 9, 4, 7, 4, 0, 6, 5, 4, 4, 4, 4, 2, 7, 8, 6, 1] expected
[6, 3, 9, 2, 9, 0, 7, 7, 5, 4, 9, 1, 7, 6, 4, 5, 6, 0, 9, 6, 6, 3, 9, 2, 4, 5, 7, 3, 8, 1, 2, 9, 4, 7, 4, 0, 6, 5, 4, 4, 4, 4, 2, 7, 8, 6, 1] my result

[1, 4, 7, 5, 6, 0, 8, 1, 0, 6, 6, 5, 2, 2, 6, 2, 7, 4, 7, 0, 2, 3, 8, 4, 0, 9, 8] input
[1, 4, 7, 5, 6, 0, 8, 1, 6, 6, 5, 2, 2, 6, 2, 7, 4, 7, 2, 3, 8, 4, 9, 8] expected
[1, 4, 7, 5, 6, 0, 8, 1, 6, 6, 5, 2, 2, 6, 2, 7, 4, 7, 0, 2, 3, 8, 4, 9, 8] my result

Thanks

I am an idiot who can't read questions properly. Thank you v much for your help, that was a simple fix in the end, and sorry for wasting your time!

Same issue as others

Yes, but as some others should have done you should read more carefully the description:

How many years does the town need to see its population greater or equal to...

Print some results and see what is the population for "50".
