Question
Arun is working on a program to swap the values of two variables, a and b, without using a temporary variable. Write a program to help Arun accomplish this task.
Solution
Sure, here is a simple program in Python that swaps the values of two variables without using a temporary variable:
# initial values
a = 5
b = 10
# print initial values
print("Initial values: a =", a, ", b =", b)
# swapping
a, b = b, a
# print swapped values
print("Swapped values: a =", a, ", b =", b)
In this program, the line a, b = b, a is where the swapping happens. This is a feature of Python where you can assign values to variables in this way. It first creates a tuple (b, a) on the right side, then immediately unpacks it to the variables on the left side. This effectively swaps the values of a and b without needing a temporary variable.
