We are glad to invite you to participate in Codeforces Round #449 (both Div. 1 and Div. 2) which will be held on December 2, 17:05 MSK.
This round is about the happiest girl in the world — Chtholly Nota Seniorious~!
You will help Chtholly, Nephren, Ithea and Willem (characters in the great novel and anime "What are you doing at the end of the world? Are you busy? Will you save us?") to solve some problems.
This round is our first round on Codeforces.
This round has 5 problems in each division and you have 2 hours to solve them.
The scoring will be announced shortly before the start of the contest.
The contest is rated for both Div. 1 and Div. 2 contestants.
It's recommended for both divisions to read through the Interactive Problems Guide before the round.
Wish everyone high rating and accepted submissions!
