--description--

For any N, let f(N) be the last five digits before the trailing zeroes in N!.

For example,

9! = 362880 so f(9)=36288

10! = 3628800 so f(10)=36288

20! = 2432902008176640000 so f(20)=17664

Find f(1,000,000,000,000)

--hints--

euler160() should return 16576.

assert.strictEqual(euler160(), 16576);

function euler160() {

  return true;
}

euler160();
