title: Return the balanced brackets if returning false
body: <p>I’m currently working on a project that basically checks if the given string of brackets is balanced or not e.g:
  {()} returns true
  {(}) returns false
  I already have this but is there a way to return the actual string if it returns false? e.g.
  {() returns {()}? If you can point me to a website or something that would be greatly appreciated</p>
