Description:

If we look at the following code:

  def getOrElseBoolean(config: Map[String, String], key: String, defaultValue: Boolean): Boolean = {
    if (config.contains(key)) {
      config(key).toBoolean
    } else {
      defaultValue
    }
  }

, we can see that the result is true only if the given key exists and its value is true.

This can be expressed using code:

config.get(key).exists(_.toBoolean)

How do you solve it?
