  Problem:
  
      The function odd_prod takes an integer n as input.
      It should multiply all of the odd numbers from 1 to n (inclusive)
      and print out the answer.
  
      E.g. odd_prod(11) = 1 * 3 * 5 * 7 * 9 * 11
  
  Tests:
  
      >>> odd_prod(11)
      10395
      >>> odd_prod(25)
      7905853580625
      >>> odd_prod(43)
