Problem: Write a program that takes as input two complex numbers and performs one of the following operations on them: addition, subtraction, multiplication, or division. The output should be the result of the operation, with 3 digits after the decimal point. The input should be two pairs of floating-point numbers indicating the real and imaginary parts of the complex numbers, separated by spaces, followed by a letter indicating the operation to be performed. The output should be two space-separated numbers, with the real part followed by the imaginary part.

Problem: Write a program that takes as input two complex numbers and performs one of the following operations on them: addition, subtraction, multiplication, or division. The output should be the result of the operation, with 3 digits after the decimal point. The input should be two pairs of floating-point numbers indicating the real and imaginary parts of the complex numbers, separated by spaces, followed by a letter indicating the operation to be performed. The output should be two space-separated numbers, with the real part followed by the imaginary part.
