title: Is there a way to find sum of digits of 100!?
body: <p>I know there is a way of finding the sum of digits of 100!(or any other big number's factorial) using Python.  But I find it really tough when it comes to C++ as the the size of even <strong><em>LONG LONG</em></strong> is not enough.</p>
  
  <p>I just want to know if there is some other way.</p>
  
  <p>I get it that it is not possible as our processor is generally 32 bits. What I am referring is some other kind of tricky technique or algorithm which can accomplish the same using the same resources.</p>
