This is a Python Program to exchange the values of two numbers without using a temporary variable.

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

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

2. Store the values in separate variables.

3. Add both the variables and store it in the first variable.

4. Subtract the second variable from the first and store it in the second variable.

5. Then, subtract the first variable from the second variable and store it in the first variable.

6. Print the swapped values.

7. Exit.

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)

1. User must first enter the values for both the elements.

2. The first element is assigned the sum of the first two elements.

3. Second element is assigned the difference between the sum in the first variable and the second variable, which is basically the first element.

4. Later the first element is assigned the difference between the sum in the variable and the second variable, which is the second element.

5. Then the swapped values are printed.

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
