title: Comparing Logical Conditions
body: <p>There are two logical conditions :</p>
  
  <pre><code>A. ( Ls != Ec &amp;&amp; Ls != Uc &amp;&amp; Ls != Rfc )
  
  B. (!(Ls==Ec || Ls == Uc || Ls == Rfc))
  </code></pre>
  
  <p>Variables are Ls, Ec, Uc, Rfc ( integers )</p>
  
  <p>I found that both conditions are logically Same.</p>
  
  <p>My Question/s is(are!)  :</p>
  
  <p>Is there any online tool/web to check multiple/two logical conditions ?
  And perfomance wise which is better generally or with repect to C# .NET 3.5</p>
  
  <p>Thanks.</p>
