title: Scala make List of strings from char array
body: <p>Here's what I'm trying to do:</p>
  
  <pre><code>val StringSpace = charList.reduce(_ + _ + _ + _ + " ")
  val StringList = //Tokenize StringSpace with " "
  </code></pre>
  
  <p>but it returns missing parameter type within first line.</p>
  
  <p>So how can someone actually join lists into half or quarter size in scala?</p>
  
  <p>e.g: From</p>
  
  <pre><code>List ("a" , "b" , "c" , "d" , "e" , "f" , "g" , "h")
  </code></pre>
  
  <p>To:</p>
  
  <pre><code>List("abcd", "efgh")
  </code></pre>
