Hello, Codeforces.

I'm going to prepare for regional contest. So why? Because I want to go republic contest and get a GOLD. But you're saying But, what's matter?

Let's discusiss.

1. I need to do more practice to solve problems. (For this state, give me please problems that uses data structure. Not too hard or too easy)

2. Solving problems faster and clearly. (To compete with your opponents and not to try cheating.)

3. Don't be LAZY! :)
