Hello everybody,

I am looking for training camp. What camps are in your countries? Can you give me the link of their websites?

Happy New Year everyone !

I want to direct your attention to tutorials . They are not as detailed as they are needed . Last contests' tutorials (Good bye & CR#221) look like written in 30 minutes . Some of problems are explained well , but others are hard to understand even after reading more explanation in comments . For example : "221 Div1 C" & "Good Bye E" tutorials of this problems are just hints in my opinion .

I want to ask authors of this problems to update tutorial and write it more detailed . I am lazy to analyze other contestants' codes as they are in writing tutorials .

Hello I have never used pointers to build a binary tree , I always used arrays . I want to build an interval (where elements can be added between queries , not segment ) tree with pointers and need your help . I can't understand why people write any functions or procedures in the structure of pointer. If you know , please link any tutorial which can help me to study the syntax of pointers .

Anybody explain me what the shit is this "Denial of judgement" ? I am writing virtual contest , sending the code and receiving this message.

Can anybody explain me the solution of this problem ?
