My code is quite dense. I usually end up with a solution without explicit loops, I use comprehension where possible without intermediate variables. This is hard to debug, so I usually start with some loop and then refactor it on the way. The variable names are usually abbreviated as follows: t: table, s: solution (sometimes intermediate), s1, s2: solutions (parts 1 and 2), xs, ys: input data.

Python
