Please explain how the swapping is done here
Hello @kumarpratikkant,
In this the swapping is done without using temporary variable and using bitwise XOR operation which is ^ operator.
The XOR of two numbers x and y returns a number that has all the bits as 1 wherever bits of x and y differ.
For example:
Initially
x=10 bit representation: 1010
y=5 bit representation:0101
Now
x = x ^ y x now becomes 15 (1111)
y = x ^ y y becomes 10 (1010)
x = x ^ y x becomes 5 (0101)
Afterwards
So you see using bitwise XOR(^) operator we have made x=5 and y=10.
