I completely missed it this year. How was the reduced length? Did he make them harder to compensate or easier to placate the crying redditors?

9 easy problems
1 moderate problem
1 problem that's hard to solve on your own but easy if you use an external solver for the NP-hard part
1 problem with a troll input such that a brute force that should by all means be too slow in addition to being painful to write up just happens to run fast, or you can skip it completely with some basic heuristic
