As you all know, Rhodoks have made a little mistake, placing the solutions of Div.1 C and Div.1 E in the contests blog. He must of course be disappointed of himself, thus, I gathered some suggestions which might help him not to make similar mistakes in the future.

1. Don't stay in the bathroom for too long.
2. Don't bring any cellphones, laptops, and anything capable of playing videos with yourself to the bathroom.
3. Throw away your headphones, let everybody hear the video you are playing.
4. Take more cold showers.
5. Exercise more. Don't spend your energy in other ways.
6. Use soaps, shampoos, etc only for washing yourself.
7. Be careful of your thoughts and your hands.

The stated suggestions will prevent you from performing actions which might harm your memory and your eyes, hope their were helpful.

A message for dear Monogon, BledDest and PurpleCrayon

Today I want to introduce you a very good programming website, by which you can improve your programming skills. Here is the link to the website, I highly recommend it:

It seemed that a user called yyhs123 has cheated in a recent contest. However, this blog is not an ordinary blog nagging about cheaters, it is a message sent by UPS (United Pedaret States) announcing yyhs123's father is going to be eaten by Shrek.

This is the exact announcement Shrek made today:

"I was told user yyhs123 has cheated in the previous contest. By the laws of the UPS government, his father is condemned of being eaten by me. The penalty will be executed as soon as possible."

Shrek, the president of UPS:

You should be more cautious with your curiosity. It might have bad consequences for you in the future.

int is a variable type in C++ which can hold an integer between $$$-2^{31}$$$ and $$$2^{31}-1$$$. You can define them in the following manner:

int a; where a is your integer’s name.

Here are three lessons I've learned during contests. Hope they help you with your future contests:

• If you solve more problems during a contest, you get a better rating
• The first problem is usually the easiest
• Wrong answers get you a penalty and have negative effect on your rating.

Did you know Codeforces is a competitive programming website?

Today I want to introduce the most essential code template, by which you can easily become red from a newbie. Copy and paste this template to every .cpp file you create:

#include<iostream>
using namespace std;

int main() {
    return 0;
}
