Python Program:

- To swap 2 numbers using XOR operator

Example:

User Input
1st number: 3
2nd number: 5

After Swap, Output:
1st number : 5
2nd number : 3

n1=int(input("Enter 1st number : "))
n2=int(input("Enter 2nd number : "))  

n1^=n2
n2^=n1
n1^=n2

print("After Swap");
print("1st number :",n1,"\n2nd number :",n2);

Output:

  Enter 1st number : 7
  Enter 2nd number : 15
  After Swap
  1st number : 15
  2nd number : 7

Program

puzzle

We are using binary XOR operator (^)

#Lets take n1=7, n2=3
 n1^=n2  #Here n1=4, n2=3
 n2^=n1  #Here n1=4, n2=7
 n1^=n2  #Finally n1=3, n2=7

Remember :
 A B A^B
 0 0  0
 0 1  1
 1 0  1
 1 1  0
