title: LinkedList toString method; converting to a single string?
body: <p>I'm trying to convert the values of a linked list's nodes into a single string. For example: </p>
  
  <pre><code>"c" -&gt; "a" -&gt; "t"
  </code></pre>
  
  <p>So when I use the built in <code>toString</code> method, I get this as an output.</p>
  
  <pre><code>"[c, a, t]"
  </code></pre>
  
  <p>Where the entire thing is a string. Is there any method that allows me to merge this into a single string, like so?</p>
  
  <pre><code>"cat"
  </code></pre>
