If the len(r)%3 == 0 then why you should add 30 more minutes ? The job is basically done. No rest need.

I have solved a 4kyu kata with fib via "Matrix Exponentiation" method. If you require this method or even "Fast Doubling" method it should be a higher lvl kyu for sure.

I have a time failure. My time complexity is O(m). Is it supposed to perform even better ?

Hi @donaldsebleung
I appreciate your help. I ve done some discussions in the forum but nobody replied. Can you send me a simple example for a kata ?. How a complete kata should look like

Guys I need someones help. Im trying to publish my own kata. The task is to create a recursion function which does something but the problem is that I dont know how to stop cheaters from using while or for loops.
Anyone knows what to do ?
Thanks

I have exactly the same error. When I decompose a number n into its prime factors I should take the biggest powers of its prime and then dived by the next prime and so on. In this case the biggest power is of 2 is 31. I can say it differently. The number 3^10 * 5^6 * 7^3 * 11^2 * 13 * 19 * 23 is diveded by 2 (9 more times), so I cant move on to the next prime (3) till I end the devision by 2.
Thanks for your time.

My code works fine in Pycharm, but here I got a ValueError:

Traceback (most recent call last):
File "main.py", line 25, in
test.assert_equals(solve_eq([[4, -3, 1, -10], [2, 1, 3, 0], [-1, 2, -5, 17]]), [1, 4, -2])

File "/runner/frameworks/python/cw-2.py", line 18, in expect
if passed:
ValueError: The truth value of an array with more than one element is ambiguous. Use a.any() or a.all()

Anyone can help ? Thanks

the 'else' statment is useless. Type just 'return Balance', because there isnt other case.
