Problem Statement

Comma quibbling is a task originally set by Eric Lippert in his blog.

Write a function to generate a string output which is the concatenation of input words from a list/sequence where:

Test your function with the following series of inputs showing your output here on this page:

Note: Assume words are non-empty strings of uppercase characters for this task.

Let's start with the solution:

Step by Step solution about How to resolve the algorithm Comma quibbling step by step in the Scala programming language

Source code in the scala programming language

def quibble( s:List[String] ) = s match {
  case m if m.isEmpty => "{}"
  case m if m.length < 3 => m.mkString("{", " and ", "}")
  case m => "{" + m.init.mkString(", ") + " and " + m.last + "}"
}

// A little test...
{
  println( quibble( List() ) )
  println( quibble( List("ABC") ) )
  println( quibble( List("ABC","DEF") ) )
  println( quibble( List("ABC","DEF","G","H") ) )
}
