A great source of interesting problems and endless competition.
Winning the 2014 Topcoder Open. Would love to defend the title!
I love many kinds of sports including, but not limited to, competitive programming.
Stay motivated and do whatever you enjoy.
I heard about Topcoder back when I was 11 from some friends of mine. At that time I used Pascal as my primary language, but I had to learn C++ to take part in Topcoder SRMs — it was fun! Several years later I won the Topcoder High School championship, but still couldn't take part in the TCO due to the age restriction.
