Title: If I read it correctly, the leader of the scoreboard submitted the solution for problem A in 7 minutes, problem B 11 minutes later, problem C 7 minutes later. (see http://code.google.com/codejam/contest/scoreboard?c=90101#)<p>I was expecting some people to be way, way faster than me, but that seems stunning. Can't wait to see what programming language they used.<p>Me, I tried to solve the problems in Ruby. I am not that experienced with Ruby, so I lost a lot of time debugging. My solution for problem A was too slow in Ruby 1.8 (only 8 minutes are allowed for computation) and only barely made it with Ruby 1.9 - Google Q&#38;A claimed it should be doable in less 8 minutes with Ruby 1.8, though.<p>In general I had no problems thinking of an algorithm (except maybe some really clever optimization), but I can't imagine coding them in 7 minutes. My solution for problem B is 93 lines long - even just typing it might take longer than 7 minutes...<p>I did not practice at all - perhaps with more practice of the typical class of problems for such competitions, it becomes more of a copy+paste thing?
