**Inputs:**
1. A complex number $x = a + bi$.
2. A complex number $y = c + di$.
**Goal:**
Return the product of $x$ and $y$ as a complex number.

<summary><b>Need a hint?</b></summary>
Multiplying complex numbers is just like multiplying polynomials. Distribute one of the complex numbers:
$$(a + bi)(c + di) = a(c + di) + bi(c + di)$$
Then multiply through, keeping in mind that $i^2=-1$, and group the real and imaginary terms together.
