Need for Annoying Problems

Правка en1, от balbit, 2020-01-05 07:18:35

Dear All,

Please recommend some annoying, implementation-heavy, and case-loaded Codeforces problems.

It will be even better if there exists an obvious solution that is very hard to implement and also a clever solution (with the same time complexity) that is easier to implement.

Basically, recommend any problem that you were very confident you could solve but somehow landed 5 WA verdicts and/or left in rage.
