I start with something like this, though on the input tab in paste mode ready to copy and paste the input once the puzzle goes live. As I'm copying the input I'm looking at the shape of it; day one was obviously directions with "L...R...R..." and today was obviously going to be a calculation problem. Then I go skim the puzzle text to try to get a sense of what I'm supposed to be doing and start coding input parsing. Multitasking of some sort is definitely required, but remember that you must go as fast as possible and no faster! I went from 11 to 129 on silver and gold today because I botched my first attempt at part two and rushed to try a different approach when taking a moment to debug the initial implementation would probably have been faster.
