Python program for addition and subtraction of complex numbers
Given two complex numbers z1 and z2. The task is to add and subtract the given complex numbers.
Addition of complex number: In Python, complex numbers can be added using + operator.
Examples:
Input: 2+3i, 4+5i
Output: Addition is : 6+8i
Input: 2+3i, 1+2i
Output: Addition is : 3+5i
Example :
Python3
def addComplex( z1, z2):
return z1 + z2
z1 = complex ( 2 , 3 )
z2 = complex ( 1 , 2 )
print ( "Addition is : " , addComplex(z1, z2))
|
Output:
Addition is : (3+5j)
Time Complexity: O(1)
Auxiliary Space: O(1)
Subtraction of complex numbers: Complex numbers in Python can be subtracted using – operator.
Examples:
Input: 2+3i, 4+5i
Output: Subtraction is : -2-2i
Input: 2+3i, 1+2i
Output: Subtraction is : 1+1i
Example :
Python3
def subComplex( z1, z2):
return z1 - z2
z1 = complex ( 2 , 3 )
z2 = complex ( 1 , 2 )
print ( "Subtraction is : " , subComplex(z1, z2))
|
Output:
Subtraction is : (1+1j)
Time Complexity: O(1)
Auxiliary Space: O(1)
Approach#3: Using to different functions
Algorithm
1.Read the two complex numbers from the user.
2.Define a function to add two complex numbers.
3.Define a function to subtract two complex numbers.
4.Call the two functions with the two complex numbers as arguments.
5.Print the results.
Python3
def complex_addition(num1, num2):
return num1 + num2
def complex_subtraction(num1, num2):
return num1 - num2
num1 = complex ( 2 , 3 )
num2 = complex ( 1 , 2 )
addition = complex_addition(num1, num2)
subtraction = complex_subtraction(num1, num2)
print ( "Addition is :" , addition)
print ( "Subtraction is :" , subtraction)
|
Output
Addition is : (3+5j)
Subtraction is : (1+1j)
Time Complexity: O(1) (constant time complexity for addition and subtraction of complex numbers)
Auxiliary Space: O(1) (constant space complexity as we are using only two variables)
