Hello, Codeforces!

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.
