You are given a tree. Each node has a value. You need to choose three distinct paths in the tree. Let's suppose that

P1= sum of path 1, p2 = sum of path 2, P3 = sum of path 3

Print minimum and maximum possible value of

|P1-P2| + |P2-P3| + |P3-P1|

Constraints 3<= n <= 2e5

_ Hierarchy in branches in B.Tech in IITs is a topic that has been widely debated in recent years. While some argue that it is necessary to maintain a certain level of standard and quality of education, others believe that it creates unnecessary stress and competition among students. In this blog post, I will be criticizing the presence of hierarchy in branches in B.Tech in IITs, and explaining why it is detrimental to the overall academic and personal development of students. One of the main arguments against the hierarchy in branches in B.Tech in IITs is that it creates a culture of competition among students. Students are constantly competing with each other for grades, internships, and job opportunities. This can lead to a high level of stress and anxiety among students, which can negatively impact their mental and physical health. Another problem with the hierarchy in branches in B.Tech in IITs is that it can limit the academic and personal development of students. Students who are not in the top branches may feel discouraged and demotivated, which can prevent them from reaching their full potential. Additionally, students who are in the top branches may become overconfident and complacent, which can also prevent them from reaching their full potential. Furthermore, the hierarchy in branches in B.Tech in IITs can also lead to a lack of diversity and inclusivity within the student body. Students from different backgrounds and with different interests may feel excluded and marginalized if they are not in the top branches. This can create a homogenous and narrow-minded student body, which is not conducive to a healthy and vibrant academic community. In conclusion, the presence of hierarchy in branches in B.Tech in IITs is problematic for a number of reasons. It creates a culture of competition and stress among students, limits their academic and personal development, and leads to a lack of diversity and inclusivity within the student body. It is important for IITs to rethink their approach to branches and find ways to promote a more inclusive and holistic academic environment for all students. _

I can't see any div3-div4 in contest. I have been waiting since a long time now. Is there anyone who can guess a date on which we expect a div-3 or div 4

This person littlejuruo is going to beat the legend sparky master. Everyone must go to his profile and upvote his blogs and comments so that he lost the game.

We must do this to make all his work go in vain.

Thank you

This person Sneh_Patel_0701 has cheated very badly that now he is going to become expert. you can see for G even the template is not same. Sir, MikeMirzayanov some people are trying hard to reach that blue colour and some are just getting it for no efforts. please ban these people so that the cheaters will think twice before cheating. A humble request!

This person sneh_patel_0701 cheats in almost all the rounds but still didn't get caught. and now he is going to become expert. That's the reason i have written the blog.

Thank you

Why is there such a long drought of division 2 contests? I want to be able to compete more frequently and see my rating improve.

So let me introduce you the best rating system which i have ever seen. So you guys must be thinking about the best codechef. which has the best rating system. you guys are smart.

So in the previous starters i found something very good. see this person had got 1st rank globally in the last DIV 2 round and his ratings changes from 1752 to 1934 an increase of 182 where as this person had 5th rank in the contest and he got from 1768 to 2239 which is basically an increase of 471 and he became a 6 star coder in a DIV 2 contest whereas the first person wasn't able to become even a 5 star.

And now see this, this person had 13th rank and his rating changes from 1721 to 1731 which is a massive increase of 10.

I would suggest atcoder, codeforces, topcoder, leetcode etc.. to change the rating system and follow codechef it's the best.

i would like to hear everyone's suggestion on this topic. Do you also feel that codechef system is too good ?

Well from the past 3-4 contests i have seen that people cheat in a way such that plagiarism can't do anything because their friends help them or the participants ask for someone's help.

So basically 2 people are giving contest with an account

For example this person aarjaviy was solving the first 3 problems in today's contest and his friend or maybe who was helping him was in D. he did the first 3 problems in c++ and his friend did the 4th problem for him in python.

I know we can't take action against such people. but seeing this thing in almost every contest i get upset.

It's not about this user only there are others too. It's just unfair and it disappoints me.

you guys will get nothing with these ratings. you are just ruining the environment here.

why you guys can't participate with your own skills.

I was solving yesterday's c with a different approach. To solve it with my technique what i need to know is:

Let's say we have a string 's' of length 'n' with parenthesis ('(' or ')') and we have queries with 'L' and 'R' (1<=L<=R<=N).

we need to tell whether the substring from L to R is balanced or not.

Is there any way to solve the queries in constant time or lets say log(n) time?

Please Help.
