title: Storing a Big Number in a Variable and Looping
body: <p>How can i store a big number in a variable and use a for loop?<br>
  I have a very big number <code>75472202764752234070123900087933251</code> and i need to loop from 0 to this number!<br>
  Is it even possible to do this? how much time will it take to end?  </p>
  
  <p><strong>EDIT:</strong> i am trying to solve a hard problem by brute force. its a combination problem.the bruteforcing cases may reach 470C450.<br>
  so i guess i should use a different algorithm...</p>
