### 例

A complex number is a string expression resulting in the form "a+bi" or "a+bj", where a and b are numbers.

If the complex number is actually a real number (b=0), then it can be either a string expression or a number value.

The function always returns a string representing a complex number.

If the result is a complex number with one of its parts (a or b) equal to zero, that part is not displayed.

The imaginary part is equal to zero, so it is not displayed in the result.

The result is presented in the string format and has the character "i" or "j" as an imaginary unit.
