    capitals.put("pak", "islamabbad")
    capitals.put("India", "New Delhi")
    capitals.put("United States", "Washington")
    capitals.put("England", "London")
    capitals.put("Australia", "abcd ")

    val result = capitals.toList().sortedBy { (_, value) -> value}.toMap()

    for (entry in result) {
        print("Key: " + entry.key)
        println(" Value: " + entry.value)
