title: Compare two integers using bit operator
body: <p>I need to compare two integer using Bit operator. 
  I faced a problem where I have to compare two integers without using comparison operator.Using bit operator would help.But how? </p>
  
  <p>Lets say 
  a = 4;
  b = 5;</p>
  
  <p>We have to show  a is not equal to b. 
  But,I would like to extend it further ,say,we will show which is greater.Here b is greater..</p>
