Write a python program to swap two numbers without using third variable.

 Program:-

a=int(input("a="))

b=int(input("b="))

print("Values before swapping\n","a=",a,"b=",b)

a=a+b

b=a-b

a=a-b

print("Values after swapping\n","a=",a,"b=",b)

Output:-

a=2

b=3

Values before swapping

a= 2 b= 3

Values after swapping

a= 3 b= 2
