scala略入門的寫法
val sort_array = List("dog",
"google",
"facebook",
"internationalization",
"blabla").sortWith(_.length<_.length)
sort_array.filter(_.length == sort_array.last.length).foreach(println)
List("dog",
"google",
"facebook",
"internationalization",
"blabla").map(str=>(str,str.length)).maxBy(_._2)._1
