Really nice Kata. It shows that prime number are cool and give us many funny exercises. Made in C++.

I've read here that instruction was written too poorly. From my point of view it was quite nice to read. I enjoy your Katas a lot.

Nice but very easy Kata. It shouldn't be 4 Kyu in my opinion. C++

Great Kata! A Stunning example which showing that even a very fast computer is too slow to execute unefficient algorithm.
It took me quite much time today, at the begining I was happy with my O(n) complexity but it still wasn't enough, I finally noticed something and solved that as author of Kata. Goodluck to everyone!

Everything is correct now. Thx for help :)

So now, I have no idea. Look at that:
Expected: [ 216, 75318, 3844615327538216960 ] Actual: [ 216, 75318, 0 ]

Output of n_Th_ product from my compiler when overrange: (400,4) try:

Hi, I am solving this Kata in C++,

in random tests there is possible that product od found numbers is bigger than long type range. What can you advice me? :)
