Objective – Given two numbers, swap both the numbers using XOR operators.

Example :

X = 4, Y = 8
Output: X = 8, Y= 4
Approach : XOR operator

There are many ways to swap two numbers but here we will discuss a solution to swap numbers using XOR(^) operator.

Say numbers are x and y.
Do x = x XOR y, this will set only the bits which are set either in x or in y. store it in x.
Do y = x XOR y, this will set the bits which were set in original x so this will store the original value of x into y.
Do x = x XOR y, this will set the bits which were set in original y so this will store the original value of y into x.
See the Example below

Java Code: Run This Code

Output:

x: 4, y: 8
After swapping
x: 8, y: 4
