Hello everyone.
I just noticed that CF1648E has an easier approach , using Boruvka's algorithm.
Can anyone prove that the run time of this algorithm is O(ElogV)?
Thanks for reading!
Hi Codeforces Community!
I am currently a high school student and an olympiad participant.
It may sounds silly , but I just wonder , what's the meaning of doing CP? One of my seniors once told me , many algorithms which are well-known for competitive-programmers turned out to be useless in reality.
I love CP , but is it really worthy to spend so much time doing it?
Thanks for advance.

I became Candidate Master last round , but my color is still blue , why?
Hi! Codeforces Community!
I want to ask a question , it is not related to Competitive Programming , but to ask how to learn English well.
I think most of the members of the community are not native English speakers , but many of them can express their ideas and share their opinions of the problems.
So , how to improve my English?
Hello Codeforces Community! I am Yifan Bao from China. I started to do cp about 2 years ago.
I think I solved many problems. Some of them are hard , such as div1 DEF , but I often read the tutorial when solving these hard problems. I also learned a lot of algorithms.
I find it hard for me to reach master or higher levels. Also I always cannot solve logic problems(I cannot express it well , maybe constructive algorithms?). Am I not talented? Are there any methods that can help me improve my skills quickly? Thanks in advance!
(sorry for my poor English
