The Hacker Cup is an annual algorithmic programming contest open to hackers from around the world. Thousands will enter, but only one will emerge as world champion. Facebook will fly the top-scoring 25 competitors to Palo Alto, California, for the final round of competition on March 11, 2011, where they’ll receive some great cash prizes and other awesome goodies. The top 300 participants from Online Round 2 will receive an official Hacker Cup t-shirt. $5,000 USD, $2,000 for 2nd place, $1,00 for 3rd, and $100 for 4th through 25th.
