Problem 435

[LarryBlake]

Shouldn't the problem read...

Define the polynomials ... f_ixⁱ⁺¹ for 0 ≤ i < n.

[mdean]

The problem looks to be fine as it is. Remember, the first term is $0x^0$.

[LarryBlake]

EDIT: mdean, you are correct, but I could swear it used to say that f₀ is defined as 1.

Actually we keep track of the last update of every problem and by whom.
For this problem it reads:
Release Date: Sat, 7 Sep 2013, 16:00
Last Update: Fri, 6 Sep 2013, 04:24 by kevinsogo
So the public version is still the same as when the problem was first published.

So it's better not to swear unless one is absolutely sure.

This problem totally throws the "one minute rule" out the window, as well as a bunch of other ones as well, such as how your PC only needs to be average at best.

I'm done with PE.

I guess it depends on the algorithm you use. My own implementation takes 0.04 second, well under one minute, on any PC, phone or intelligent watch you may own.

Could someone please clarify the meaning of this problem? Specifically, I am not sure what is meant by the final (=15!).

Thanks.

15!=1307674368000
(15! means factorial(15); see https://en.wikipedia.org/wiki/Factorial)

[mbh038]

Of course, yes. Thanks.
