(Ruby) When the weights are the same ie: "30KG", "30000G", "30KG" only the order that starts with KG is accepted: "30KG", "30KG", "30000G".
Also "90000G", "90KG" is not acceptable, but "90KG", "90000G" is.

Ruby: on the test's if I had raise "Error" if (wrong type,etc)...then the tests would fail.
But if I put return "Error" if (wrong type,etc) they passed. The opposite is true for final submission.

I hit submit a few more times and it worked. Whatever.

I'd have this kata solved in ruby except out of the hundreds of scores one improvement is -57.49999999999999. 13 nines rounds to -57. If my value had 14 nines then it would round to -58, which is the answer for the test case.

I was not able to pass final submission. All of my test cases work in IRB. I have more than a few katas in my unfinished pile that work in IRB & I think should work. Let me know if you get it to work.

Has anyone solved this in Ruby? I keep coming back to this one and cannot get a solution that does not time out.

ah, subtract in kind to only leave positive values.

how can [1,0] and [0,1] yield the same answer? (1)?

(Ruby) cannot pass the invalid string input tests (only for submit, test button works). If I return 'error' or false, I still get: "The function somehow worked with wrong input"

"6F43E8"
"Error"
The function somehow worked with wrong input
"1234 "
"Error"
The function somehow worked with wrong input
""
"Error"
The function somehow worked with wrong input

Not sure why this is failing (ruby). On the second to last test, the expected result for (:player2=>[[5, 5]]) isn't even on the input array to the function.

Creature battles
[[1, 1]]
[[1, 1]]
Test Passed: Value == {:player1=>[], :player2=>[]}
[[2, 2]]
[[1, 1]]
Test Passed: Value == {:player1=>[[2, 2]], :player2=>[]}
[[1, 1]]
[[2, 2]]
Test Passed: Value == {:player1=>[], :player2=>[[2, 2]]}
[[1, 1], [2, 1], [2, 2], [5, 5]]
[[1, 2], [1, 2], [3, 3]]
Test Passed: Value == {:player1=>[[5, 5]], :player2=>[[1, 2], [3, 3]]}
[[1, 2], [1, 2], [3, 3]]
[[1, 1], [2, 1], [2, 2]]
Expected: {:player1=>[[1, 2], [3, 3]], :player2=>[[5, 5]]}, instead got: {:player1=>[[1, 2], [3, 3]], :player2=>[]}
[]
[[1, 1], [2, 3], [10, 10]]
Test Passed: Value == {:player1=>[], :player2=>[[1, 1], [2, 3], [10, 10]]}

I can't figure out the prbblem here (ruby). On final submit i get the error message: (page_index returned incorrect value when provided a item_index argument that was out of range)
Even though all of my tests pass?!
Test.assert_not_equals(helper.page_index('f'), 3)
Test.assert_equals(helper.page_index('f'), 1)
Test.assert_equals(helper.page_index('a'), 0)
Test.assert_equals(helper.page_index(-12), -1)
Test.assert_equals(helper.page_index('bollocks'), -1)
Test.assert_equals(helper.page_index(nil), -1)
Test.assert_equals(helper.page_index(false), -1)

Ah, thanks. Despite trying a few different approaches I can't get the final calculation done in under 6 seconds. Some of the requirements of these problems are very opaque.

My (Ruby) solution passes all test on this website & my own, yet get error message:
each': failed to allocate memory (NoMemoryError) from to_a' from solution' from block in
'
from wrap_error' from it'
from it' from

Ugh. Infuriating.
