  <p>I want to find all matched elements between <code>list1</code> and <code>list2</code>. When I change <code>list1</code> and <code>list2</code> with counter, it is not find all element, but only shows match one element. </p>
  
  <p>This could displays all elements, but I can't find how many elements.</p>
