        <script src= 
        "https://ajax.googleapis.com/ajax/libs/angularjs/1.4.2/angular.min.js"> 
        </script>     
        </head> 
    <body ng-app="app" style="padding:20px">

      <h2 style="">ng-value Directive</h2> 
      <p>Choose one:</p> 
      <div ng-controller="geek"> 
          <div ng-repeat="l in sort"> 
           <input type="radio" ng-model="my.fav" ng-value="l" name="Sort"> {{l}} 
          </div> 
          <pre>Selected choice is:{{my.fav}}</pre> 
      </div> 
      <script> 
      var app = angular.module("app", []); 
      app.controller('geek', ['$scope', function ($scope) { 
          $scope.sort = ['Merge Sort', 'Quick Sort', 'Bubble Sort'];
