Complex Number Multiplication

Description

A complex number is encoded as the string "real+imaginaryi" where:

- real is an integer in [-100, 100] representing the real component.

- imaginary is an integer in [-100, 100] representing the imaginary component.

- i² == -1.

Given two such encoded strings num1 and num2, compute their product and return the result in the same string format.

Example 1:

Input: num1 = "1+1i", num2 = "1+1i"

Output: "0+2i"

Explanation: (1 + i) * (1 + i) = 1 + i2 + 2 * i = 2i, and you need convert it to the form of 0+2i.

Example 2:

Input: num1 = "1+-1i", num2 = "1+-1i"

Output: "0+-2i"

Explanation: (1 - i) * (1 - i) = 1 + i2 - 2 * i = -2i, and you need convert it to the form of 0+-2i.
