more funny katas

if there another language not working you should try another one :V

I have failed 100 random cases and i do not know why [-9, -15, -2, -16, 18, 16, 'A', -11.143047152343609, -10, -16, -12, 7, 16, -17, 9, -18, 7, 15, -11, -3, 3, -13, 11, -18, 12.459426828479579, -13, -7.3537210160318125] should equal [], there are some float values and negative ones but what is the condition? i think description is not very helpful.

i think this kata is better than string functional compared selection (edit 5 kyu difficult aproximately)

Indeed, after some optimization all tests are OK.

the basic approach i can think of is to iterate over that given range (a, b) and check if two first numbers are primes and evaluate the other conditions but using a for loop just cause 'execution time out' it should be a way to reduce this but i think is related to some numerical theory terms

This means you need a better algorithm, yours is too slow. (Or you have an infinite loop somewhere)

"Execution Timed Out (12000 ms)"

I have defined a function 'is_prime' but each time i call this is time consumption very high, then, to take that condition of just first two digits, i have concluded that are just between 2, 100 prime numbers, then i have defined as an array of prime numbers

is there a method from math (like ceil/floor) to index correctly as string when having a lenght odd and even to accumulate sum by left-right and keep middle elements?

this kata should be 8 difficult category

same problem here, new learner so feeling stupid
