// method
  
// Creating object
object GfG
  
    // Main method
    def main(args:Array[String])
    {
      
        // Creating a map
        val m1 = Map("geeks" -> 5, "for" -> 3, "cs" -> 2)
          
        // Applying dropWhile method
        val result = m1.dropWhile(z=>false
          
        // Displays output
        println(result)
      
    }
}
