xor

The xor function compares the corresponding bits of two values. If the corresponding bits are the same, it gives 0, and if they are different, it gives 1.

Look at this example:

fun main(args: Array<String>) {
  val a=2
  val b=3
  print(a xor b)
}

Given is the output:

 1

Here's the explanation:

2 = 10 (Binary format)

3 = 11 (Binary format)

Bitwise XOR of 2 and 3

                    in binary

10 XOR 11

01 = 1 (Decimal format)
