复数可以表示为实部和虚部的和。要计算复数的和,只需要将对应位置的实部相加,虚部相加即可。
由于乘法涉及到复数的乘积,所以需要分别计算实部的乘积和虚部的乘积,并相减得到最终的实部,再计算实部与虚部的乘积并相加得到最终的虚部。
下面是一个可能的实现代码:
- # 定义一个复数类
- class Complex:
- def __init__(self, real, imaginary):
- self.real = real
- self.imaginary = imaginary
- # 重载加法运算符
- def __add__(self, other):
- real = self.real + other.real
- imaginary = self.imaginary + other.imaginary
- return Complex(real, imaginary)
- # 重载乘法运算符
- def __mul__(self, other):
- real = self.real * other.real - self.imaginary * other.imaginary
- imaginary = self.real * other.imaginary + self.imaginary * other.real
- return Complex(real, imaginary)
- # 重载字符串表示方法
- def __str__(self):
- return f'{self.real}{self.imaginary}i'
- # 输入三个复数
- c1_str, c2_str, c3_str = input().split()
- real1, imaginary1 = map(int, c1_str.split('-'))
- real2, imaginary2 = map(int, c2_str.split('-'))
- real3, imaginary3 = map(int, c3_str.split('-'))
- # 创建三个复数对象
- c1 = Complex(real1, -imaginary1)
- c2 = Complex(real2, -imaginary2)
- c3 = Complex(real3, -imaginary3)
- # 计算和
- sum_result = c1 + c2 + c3
- # 计算乘积
- multiply_result = c1 * c2 * c3
- # 输出结果
- print(sum_result)
- print(multiply_result)

输入示例:
1-2j 10 -7-j
输出示例:
4-3i
-90+130i
