Hey there! I am testing some new stuff (according to your suggestions) and playing with matplotlib (learning it to be precise), so here is a bunch of statistics (only) in some past contest (Codeforces Round 269 (Div. 2)).

Previous posts can be found here.

Stats

By "rejected solutions" we understand solutions, which didn't pass the final tests (and were tested on them).
