title: Populate hash on the fly: keys in one file and values in another
body: <p>So I have a text file with the following line:</p>
  
  <blockquote>
    <p>123456789 </p>
  </blockquote>
  
  <p>But then I have a second file:</p>
  
  <blockquote>
    <p>987654321</p>
  </blockquote>
  
  <p>So how can I make the first file's contents the <code>keys</code> in a hash, and the second file's values the <code>values</code>? (Each character is a key/value)</p>
  
  <p>Should I store each file into different arrays and then somehow merge them? How would I do that? Anything else?</p>
  
  <p>Honestly, I would give you my code I have tried, but I haven't the slightest idea where to start.</p>
