Hey there!

I think everyone know what does this piece of code do:

vector <int> v = {1, 2, 3, 4};
for (int x : v)
  cout << x << " ";

prints: 1 2 3 4

Is there any way to do this in reverse order ?!

Hey guys!
You can easily make your contest unofficial during contest. To do this you should ask your friend or someone else to give his code. Then submit it (don't change anything). After the contest your contest will be unofficial. No rating loose.

Hello everyone! I'm new on codeforces and programming. It's my first blog entry. Sorry for my mistakes. I know some algorithms but I can't use them in contests. I ask you books for easy (beginner) or (elementary) algorithms that every programmer should know. I would be glad if someone helps me to be a good programmer. I want to solve at least 3 or 4 problems from div2. I know that it is not impossible.
