SRM 600 T-Shirt

It seems that TopCoder likes to give away T-shirts in every 100 SRMs. I failed to participate in SRM 500 because I overslept that time, so I was happy when I managed to participate in SRM 600.

How I Became a TopCoder SRM Problem Writer

I have been writing SRM problems quite often in past months. It has been a very exciting experience for me. I would like to recall how I became a problem writer in this competition…
