I invite you to participate in Codeforces Beta Round #48. This time I acted as the author of the contest. I believe it is really exciting too! I urge you to follow my example. Codeforces is happy to contest authors.
With contest proposals please contact RAD (our problem coordinator).Participants are waiting for your problems!
PDF statements will be also available after the contest start. Please, use the link.
I wish you beautiful solutions,
