Print a bunch of uninteresting numbers! An uninteresting number (which I totally didn't make up only for this challenge) is created like this:


  
  Take a positive integer N
  Create a new number O by adding the digits of N at the end of N
  The final uninteresting number is O*N
  


For example for N=12:


  
  O = 1212
  O*N = 1212 * 12
  Final number is 14544
  


Input

A positive integer N (N > 0) or your language's equivalent. You don't have to catch incorrect input.

Output

The corresponding uninteresting number.
