title: How to get the difference between 2 int arrays as a percentage
body: <p>Mathematically we can solve it like Given Amount / Total Amount * 100 to get the percentage difference. But what I need is to compare 2 Integer Arrays (in C# Win App) and get the percentage of the difference.
  Like :</p>
  
  <pre><code>1 -----&gt; -2
  2 -----&gt;  3
  3 -----&gt;  7
  4 -----&gt;  456
  5 -----&gt;  13
  </code></pre>
  
  <p>These two columns are 2 Integer Arrays and I should get the difference between them.<br>
  How can I get this? A mathematical answer or an algorithm, whatever can be used to solve the problem.</p>
