Haskell and JavaScript: yes.

Tests are language-specific, so mentioning the language you're having this question in would be useful. Help us help you!

Closing.

i think math tag should be added

Your solution is absolutely wrong. It's about the separate values on the board, not their sums.

I wonder if something like cytoolz would help brute force

its in clojure and still not fixed

in what exactly am i terribly wrong?

it is irrelevant how much time he spent, it is even irrelevant who did this kata.

"It's not kyu 8 kata, it's kyu 5 and all kata of this level are expected to be solved by a more advanced algorithm than a brute force one."
where is this written?
and why is this a bad idea to write that again in description? you can obviusly see how many people try to solve it with bruteforce at first, because that is the easiest solution.

also what you think about g964 answer

the tests are designed to fail for bruteforce solutions

"Not at all..."

is it possible to solve this with bruteforce?
based on your answer i think it is not possible.

well if it is impossible then it is a condition that is implicit(if there is somewhere written that all 5 kyu cant be solved with bruteforce in any language).
why is this a problem to make this condition explicit?

You are terribly wrong here accusing the author of this kata in some sort of deceit. g964 spent time creating this interesting kata.
It's not kyu 8 kata, it's kyu 5 and all kata of this level are expected to be solved by a more advanced algorithm than a brute force one. If you are expecting naive algorithms, maybe it's not a bad idea to try kata kyu 7-8.

in clojure

first is a bad name there is already first
commas instead of spaces in vector is also bad

dunno about clojure, but in python, yes.

numbers are only from (1 or 0) to 99?

after 4 years still works
