title: Simple Spacing In Output
body: <p>I need to write a method which will take a string like <code>"1+2+3*4"</code> and add spaces between each and every character, and remove spaces if there are too many. The string passed in may have spaces / not have spaces, I need to assure there is only one space in between each character.  </p>
  
  <p>If someone could please provide the simplest and least complicated way of achieving this, I would be very grateful.</p>
