537 - Complex Number Multiplication.
Medium
A complex number can be represented as a string on the form "**real**+**imaginary**i" where:
real is the real part and is an integer in the range [-100, 100].imaginary is the imaginary part and is an integer in the range [-100, 100].i2 == -1.Given two complex numbers num1 and num2 as strings, return a string of the complex number that represents their multiplications.
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.
Constraints:
num1 and num2 are valid complex numbers.| Constructor and Description |
