title: AS3 Comparing 2 Arrays
body: <p>I'm having a hard time wrapping my head around this problem. I have 2 unsorted arrays that need to be compared, array2 must contain all elements of array1 and array2 can any number of extra elements without affecting the result. I don't see any benefits from sorting the arrays and comparing the string values as array2 can have extra information causing noise.</p>
  
  <pre><code>var array1:Array;
  var array2:Array;
  
  // array2 must contain all elements of array1.
  
  var array1:Array = new Array(1, 5, 6, 7);
  var array2:Array = new Array(5, 9, 6, 4, 7, 8);
  // comparing this should return false (array2 is missing and element from array1)
  
  var array1:Array = new Array(1, 5, 6, 7);
  var array2:Array = new Array(5, 9, 6, 4, 7, 1);
  // comparing this should return true (array2 has all the elements of array1)
  </code></pre>
  
  <p>Any help in the right direction would be greatly appreciated.</p>
