I'll look into it. There are 39 testcases in the validation process, 30 of which are randomly generated. There are only 5 example testcases, but they cover the full-range of the functionality required of the program. If I can think of other possible testcases covering alternate flows not covered, I'll be sure to update the test suite.

I missed that. I took it off. Thanks!

True. I changed the description.

The built-in function max does exactly what is required: return 1 as a minimum. However the wording 'max', I thought could be clarified a little bit more: what is required
for specifying the stack would be a bound, that is between 1-->floor(1/10 * n) and 1-->floor(1/2 * length(list_one)). 'With two or more arguments, return the largest argument' is how max is specified in Python's help doc. However, the word 'maximum(floor(1/10n),1)' could be interpreted as a ceiling of 1 or floor(1/10n); so values like 0.9 or 0.8 are permissible. I am talking about the general specification of the problem for someone who is not familiar with the function max(). So I decided to word it as greater(floor(1/10*n),1) to explicitly specify that 1 is a lower-bound.

duplicate issue

I think there is a problem with your description. You give the following example:

list_1:[count(1)=minimum(floor(1/10*n),1]
list_2:[count(1)=minimum(floor(length(list_1)/2)),1]
list_x:[count(1)=minimum(floor(length(list_1)/2)),1]
list_last:[count(1)=remaining 1s]

I believe that you want to take the maximum, not the minimum.

The javascript version of the "Mountain of Gold: Arrangement Problem" appears to be broken. The Test for this kata displays the "twoOldestAges" kata, a completely different kata.

Tests need to be more thorough.

There's a dummy JS version. It should be deleted from the editor.

How is 7 a peak?

it is not, it is the index of a peak. in this kata, you have to return an array of peaks and an array of their indices

I don't know what values take WA for x-axis there, but they are wrong. Try with this other one: https://www.wolframalpha.com/input?i=plot+%5B%280%2C3%29%2C+%281%2C+2%29%2C+%282%2C+3%29%2C+%283%2C+6%29%2C+%284%2C+4%29%2C+%285%2C+1%29%2C+%286%2C+2%29%2C+%287%2C+3%29%2C+%288%2C+2%29%2C+%289%2C+1%29%2C+%2810%2C+2%29%2C+%2811%2C+3%29%5D&lang=es

I guess OP confusion came from the wrong graphic representation.

You're looking for all the peaks (think: mountain peaks), not just the highest one. The image you showed displays them both pretty well.

I'm a little bit confused:

[Example: pickPeaks([3, 2, 3, 6, 4, 1, 2, 3, 2, 1, 2, 3]) should return {pos: [3, 7], peaks: [6, 3]} (or equivalent in other languages)]
