No, it's not

I agree with sinisake. This kata should be no higher than 7 kyu. Took me about a minute, other 5kyu kata have been far more difficult.

It would be really easy if not for all the added "Extras". I've done this several times before, but then you add in capitals being different, andthe.. "," before the i.... wait i just figured it out...

Yes, thank you!

break doesn't needed here

Huh, GREAT kata! Not too happy with my own solution, but, at least - it exists! :)

79228162514264337593543950340 should be the power of two. Few wrong tests, after all this time.

You realise ranks go down right? You at 7kyu are the second lowest rank there is.

Also, completing a kata at some level means you get points, but it does not mean you magically jump up to that level. User level and kata levels are very seperate things.

This Kata is 5 Kyu, meaning thats how many you get for completing it. If you have less than that, you haven't completed it.... If it was so easy, why didn't you complete it?

That doesn't make any difference. I just wanted to say that the rank is a relative thing. :) Btw, my rank here is higher than i deserve. Also, some 7kyu or 6kyu katas can be harder than 5kyu katas, for someone. Peace.

says the guy with 4kyu....

print(lcs('abcdefghijklmnopq', 'apcdefghijklmnobq')) #This test has broken my "solution" too.

Same here, too. Strange. But, is it actually, correct? Sum of divisors for 441 is 300, if i am right?

Ok, thanks. But how to fix it?
