How to use bitwise XOR in Scala

Answer 1

/*
  
X Y | X ^ Y
0 0 |   0
0 1 |   1
1 0 |   1
1 1 |   0
  
*/

object XORBits extends App {
  def printBits(n: Int): Unit = {
    println(String.format("%8s", Integer.toBinaryString(n)).replace(' ', '0'))
  }

  val cases = Seq((5, 5), (7, 0), (0, 6), (0, 0))

  for ((x, y) <- cases) {
    printBits(x)
    println("^")
    printBits(y)
    println("=")
    printBits(x ^ y)
    println("\n")
  }
}
