Problem Description

The program takes both the values from the user and swaps them without using temporary variable.

Problem Solution

1.         Take the values of both the elements from the user.

2.         Store the values in separate variables.

Program/Source Code

Here is source code of the Python Program to exchange the values of two numbers without using a temporary variable. The program output is also shown below.

a=int(input("Enter value of first variable: "))

b=int(input("Enter value of second variable: "))

a=a+b

b=a-b

a=a-b

print("a is:",a," b is:",b)




Runtime Test Cases

Case 1

Enter value of first variable: 3

Enter value of second variable: 5

a is: 5  b is: 3

Case 2

Enter value of first variable: 56

Enter value of second variable: 25

a is: 25  b is: 56
