How to use bitwise XOR in Kotlin

Answer 1

fun printBits(n: Int) {
    println(String.format("%8s", Integer.toBinaryString(n)).replace(' ', '0'))
}

fun main() {
    val cases = listOf(Pair(5, 5), Pair(7, 0), Pair(0, 6), Pair(0, 0))

    for ((x, y) in cases) {
        printBits(x)
        println("^")
        printBits(y)
        println("=")
        printBits(x xor y)
        println()
    }
}
