Let's solve some hard problems!

Правка en10, от ivan100sic, 2022-01-16 20:10:12

Tonight, I will pick twelve 3000 rated problems I haven't solved yet, try solving them, and track my progress. As usual, I will not look at editorials. Hopefully I will be able to solve them all before the year ends. I will not make this my highest priority and I won't try too hard. I will keep solving other problems in the meantime.

The problems are:

  1. 341E - Игра с конфетами (solved Jan 14, 12 days)
  2. 843E - Максимальный поток
  3. 1250D - Conference Problem (solved Jan 5, 3 days)
  4. 573D - Мишка и кавалерия (solved Jan 6, 4 days)
  5. 1290D - Сорта кофе (сложная версия) (solved Jan 8, 6 days)
  6. 568E - Наибольшая возрастающая подпоследовательность
  7. 788D - Поиск прямых (solved Jan 14, 12 days)
  8. 698F - Взаимно простые перестановки (solved Jan 3, 1 day)
  9. 1342F - Сделай возрастающим (solved Jan 4, 2 days)
  10. 1236F - Алиса и кактус (solved Jan 3, 1 day)
