title: How to shift letters to the right or left?
body: <p>I am given a file with a string, for example <code>"The United States was founded in *1776*"</code>. What I cannot figure out is how to shift letters one space to the left or right and have the letters wrap around. I am able to shift the letters from an a to b but not change its location within the word.
  Example of this output would be:</p>
  
  <pre><code>"heT
  nitedU
  tatesS
  asw
  oundedf
  ni
  1776**"
  </code></pre>
