Remember NO GOOGLING or searching the Internet allowed and GOOD LUCK!!!!

LWS Inc recently came out with a series of three digit combination locks. The only problem is they were slightly defective. No combinations that started or ended in a zero would work, and combinations worked whether they were entered backwards or forwards. How many combinations would a cracker have to try before they were guaranteed to find one that works?
