Scala Map foreach

Question

given:

val m = Map[String, Int](\"a\" -> 1, \"b\" -> 2, \"c\" -> 3)
m.foreach((key: String, value: Int) => println(\">>> key=\" + key + \",          


        

Answer 1

Docs says argument is tuple -> unit, so We can easily do this

Map(1 -> 1, 2 -> 2).foreach(tuple => println(tuple._1 +" " + tuple._2)))
