This webpage contains information about Associate Professor Steven Halim's courses in School of Computing, National University of Singapore titled: Competitive Programming. He teaches several programming courses in NUS, ranging from basic programming methodology, intermediate data structures and algorithms, and up to the ‘Competitive Programming’ module that uses this book. It outlines topics like data structures, sorting and searching algorithms, and the "Top Coder" coding style. The more impressive to me was the ’Methods to Solve’ from Steven Halim, a very young student from Indonesia and I started to believe that the dream would become real a day, because the contents of the site were the result of a hard work of a genius of algorithms and informatics.
