Hello everyone.↵
↵
I just noticed that [CF1648E](https://codeforces.net/problemset/problem/1648/E) has an easier approach , using [Boruvka's algorithm] (https://en.wikipedia.org/wiki/Bor%C5%AFvka%27s_algorithm).↵
↵
Can anyone prove thatwhy the run time of this algorithm is O(ElogV)?↵

Thanks for reading!
