title: Convert integer to string without access to libraries
body: <p>I recently read a sample job interview question:  </p>
  
  <blockquote>
    <p>Write a function to convert an integer
    to a string. Assume you do not have
    access to library functions i.e.,
    itoa(), etc...</p>
  </blockquote>
  
  <p>How would you go about this?</p>
