@HWK - Even if You just reached (not beat) "my" solution I could always disqualify it so that You would be the rightful leader of C in this task. ;-) |

@challenger: It's painful that you've pushed my "nice" C-solution to the second page of best solutions. :-) Edit: Back again! Last edit: 2011-05-08 08:39:09 |

Thanks Piotr. That solution was OK when perl is built with 64-bit integers, but not with 32-bit. |

Yes, for 0! You should print 1. Your mistake is that for bigger numbers You always print -1. Before submitting always check the hardest case. Here for 5*109 You should print 46323377618. |

Having trouble getting the right answer to this one. The length of 0! is 1, right? |
