Bad kata and bad description, the test cases do not take into account non-consecutive inputs and the input is an array and not a list as stated in the statement title.
nice kata!
Ruby 3.0 should be enabled.
Enabled in this fork
sometimes things are simpler than they seem
how to handle exception when array is [1, 2, 4, 5, 5]
A good light kata.
Added more tests (a set of random ones). I hope @jdwolford be ok with it. Sorry if I overstepped here, the number of js solutions was reaching the point where the tests become blocked.
I'm sorry, I can't get what you mean. What do you mean by "blocked"?

R translation kumited.
Please carefully review and approve! Comments included to help you grok R, if you're not familiar with it. Basic and example tests taken directly from python version. Random tests use the same parameters, but a slightly different structure.
.
As others have pointed out. There is no guidence on what should be returned if the input is invalid. -1 maybe? Would have made the Kata more interesting. If there is no guidance or it doesn't test for it, why even mention it.
Exactly
The description should be clearer about invalid input. Is it, that we can expect only ever to get valid input, or should we somehow react on an invalid input array? From my passing the tests without dealing with invalid input, I would expect the former. Only the instructions should say so.

Are we assuming only valid input or do we need to code for invalid values eg. [5,4,2,1,1] - would make the challenge mnore interesting if say we needed to return say -1 for invalid inputs.
Typo - dupliated should be duplicated :)
Thanks! Got it fixed.
Nice beginner kata: I translated it into both Python and Ruby, if you want to approve them :)
And let me know if you might appreciate random tests on JS too :)
Thanks got them approved.
I don't feel like random testing is needed, but I certinaly would not mind adding it. :)
