On a side note, I find writing and drawing very useful when I tried to get through some algorithm questions or similar things that need a bit of thought. Writing and drawing weed out the edge cases pretty effectively and I can better cut the question into pieces in that way. I also found that if I can't sort out my thoughts in written forms, there is no way for the code to work. Somehow it's a lot easier to setup mental barriers (to focus or to reduce problems into pieces) when I'm writing.
