Conflict between two js files

Hi,
I created web site with some js. Specifically autocomplet jquery using this manual http://jqueryui.com/autocomplete/ and map-highlite using this site http://davidlynch.org/projects/maphilight/docs/demo_features.html. I did not releaze problem until now.

  1. <script src="http://code.jquery.com/jquery-1.9.1.js"></script>
  2. <script src="http://code.jquery.com/ui/1.10.1/jquery-ui.js"></script>
  3. <script src="http://ajax.googleapis.com/ajax/libs/jquery/1.5.2/jquery.min.js"></script>
When I commenting third line autocomplete working otherwise working map-highlite. Exist some simple solution for this problem.?
