Please do not post solutions in kata discourses.

1. Please use the spoiler flag when posting something that could spoil the solution. I added it for you.
2. Your code is too slow for this task. Keep in mind that test cases check for factorials of numbers as big as 1 billion.

Try to think of a faster solution.

i so overthunk it. please god give me the strength to master 7 kyu's

no recursion.

nice

Oh, thank you! I was in a hurry without reading it completely, as always)

You're solution is to slow. Read the end of the description:

Hint: You're not meant to calculate the factorial. Find another way to find the number of zeros.

I thought my solution was very clever... then I saw this.

Not invoking it on createSecretHolder's invocation

Nice kata, but a bit overrated in my humble opinion.
It's a pure math, not testing your programming skills, so the solution is really simple.
