title: The intersection of two sorted arrays
body: <p>Given two sorted arrays: <code>A</code> and <code>B</code>. The size of array <code>A</code> is <code>La</code> and the size of array <code>B</code> is <code>Lb</code>. How to find the intersection of <code>A</code> and <code>B</code>?</p>
  
  <p>If <code>La</code> is much bigger than <code>Lb</code>, then will there be any difference for the intersection finding algorithm?</p>
